Returns the absolute value of this BigDecimal
Returns a new BigDecimal based on the supplied MathContext, rounded as needed.
Converts this BigDecimal to a Byte.
Converts this BigDecimal to a Byte. If the BigDecimal is too big to fit in a Byte, only the low-order 8 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigDecimal value as well as return a result with the opposite sign.
Converts this BigDecimal to a Char.
Converts this BigDecimal to a Char. If the BigDecimal is too big to fit in a Char, only the low-order 16 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigDecimal value and that it always returns a positive result.
Compares this BigDecimal with the specified BigDecimal
Converts this BigDecimal to a Double.
Converts this BigDecimal to a Double.
if this BigDecimal has too great a magnitude to represent as a double,
it will be converted to Double.NEGATIVE_INFINITY or
Double.POSITIVE_INFINITY as appropriate.

disagree, BigDecimal will agree with the Double value
Converts this BigDecimal to a Float.

if this BigDecimal has too great a magnitude to represent as a float,
it will be converted to Float.NEGATIVE_INFINITY or
Float.POSITIVE_INFINITY as appropriate.
Returns string formatted according to given format string.
Returns string formatted according to given format string.
Format strings are as for String.format
(@see java.lang.String.format).
Returns the hash code for this BigDecimal.
Returns the hash code for this BigDecimal.
Note that this does not merely use the underlying java object's
hashCode because we compare BigDecimals with compareTo
which deems 2 == 2.00, whereas in java these are unequal
with unequal hashCodes. These hash codes agree with BigInt
for whole numbers up ~4934 digits (the range of IEEE 128 bit floating
point). Beyond this, hash codes will disagree; this prevents the
explicit represention of the BigInt form for BigDecimal values
with large exponents.

Should only be called after all known non-primitive types have been excluded.
Should only be called after all known non-primitive types have been excluded. This method won't dispatch anywhere else after checking against the primitives to avoid infinite recursion between equals and this on unknown "Number" variants.
Additionally, this should only be called if the numeric type is happy to be converted to Long, Float, and Double. If for instance a BigInt much larger than the Long range is sent here, it will claim equality with whatever Long is left in its lower 64 bits. Or a BigDecimal with more precision than Double can hold: same thing. There's no way given the interface available here to prevent this error.
Same as the one-argument until, but creates the range immediately.
Creates a partially constructed NumericRange[BigDecimal] in range
[start;end), where start is the target BigDecimal.
Creates a partially constructed NumericRange[BigDecimal] in range
[start;end), where start is the target BigDecimal. The step
must be supplied via the "by" method of the returned object in order
to receive the fully constructed range. For example:
val partial = BigDecimal(1.0) to 2.0 // not usable yet val range = partial by 0.01 // now a NumericRange val range2 = BigDecimal(0) to 1.0 by 0.01 // all at once of course is fine too

Tests whether the value is a valid Double.
Tests whether the value is a valid Double. "Valid" has several distinct meanings, however. Use
isExactDouble, isBinaryDouble, or isDecimalDouble, depending on the intended meaning.
By default, decimal creation is used, so isDecimalDouble is probably what you want.
(Since version 2.11) Validity has two distinct meanings. Use isExactBinaryDouble or equivalentToDouble instead.
Tests whether the value is a valid Float.
Tests whether the value is a valid Float. "Valid" has several distinct meanings, however. Use

(Since version 2.11) What constitutes validity is unclear. Use isExactFloat, isBinaryFloat, or isDecimalFloat instead.
BigDecimalrepresents decimal floating-point numbers of arbitrary precision. By default, the precision approximately matches that of IEEE 128-bit floating point numbers (34 decimal digits,HALF_EVENrounding mode). Within the range of IEEE binary128 numbers,BigDecimalwill agree withBigIntfor both equality and hash codes (and will agree with primitive types as well). Beyond that range--numbers with more than 4934 digits when written out in full--thehashCodeofBigIntandBigDecimalis allowed to diverge due to difficulty in efficiently computing both the decimal representation inBigDecimaland the binary representation inBigInt.When creating a
BigDecimalfrom aDoubleorFloat, care must be taken as the binary fraction representation ofDoubleandFloatdoes not easily convert into a decimal representation. Three explicit schemes are available for conversion.BigDecimal.decimalwill convert the floating-point number to a decimal text representation, and build aBigDecimalbased on that.BigDecimal.binarywill expand the binary fraction to the requested or default precision.BigDecimal.exactwill expand the binary fraction to the full number of digits, thus producing the exact decimal value corrsponding to the binary fraction of that floating-point number.BigDecimalequality matches the decimal expansion ofDouble:BigDecimal.decimal(0.1) == 0.1. Note that since0.1f != 0.1, the same is not true forFloat. Instead,0.1f == BigDecimal.decimal((0.1f).toDouble).To test whether a
BigDecimalnumber can be converted to aDoubleorFloatand then back without loss of information by using one of these methods, test withisDecimalDouble,isBinaryDouble, orisExactDoubleor the correspondingFloatversions. Note thatBigInt'sisValidDoublewill agree withisExactDouble, not theisDecimalDoubleused by default.BigDecimaluses the decimal representation of binary floating-point numbers to determine equality and hash codes. This yields different answers than conversion betweenLongandDoublevalues, where the exact form is used. As always, since floating-point is a lossy representation, it is advisable to take care when assuming identity will be maintained across multiple conversions.BigDecimalmaintains aMathContextthat determines the rounding that is applied to certain calculations. In most cases, the value of theBigDecimalis also rounded to the precision specified by theMathContext. To create aBigDecimalwith a different precision than itsMathContext, usenew BigDecimal(new java.math.BigDecimal(...), mc). Rounding will be applied on those mathematical operations that can dramatically change the number of digits in a full representation, namely multiplication, division, and powers. The left-hand argument'sMathContextalways determines the degree of rounding, if any, and is the one propagated through arithmetic operations that do not apply rounding themselves.1.1
