Concatenates its arguments. The arguments must evaluate to atoms. The return value is a symbol if the first argument is a symbol and a string otherwise.
concat evaluates its arguments. The single quote ' prevents
evaluation.
See also sconcat, that works on non-atoms, too, simplode,
string and eval_string.
For complex string conversions see also printf.
(%i1) y: 7$
(%i2) z: 88$
(%i3) concat (y, z/2);
(%o3) 744
(%i4) concat ('y, z/2);
(%o4) y44
A symbol constructed by concat may be assigned a value and appear in
expressions. The :: (double colon) assignment operator evaluates its
left-hand side.
(%i5) a: concat ('y, z/2);
(%o5) y44
(%i6) a:: 123;
(%o6) 123
(%i7) y44;
(%o7) 123
(%i8) b^a;
y44
(%o8) b
(%i9) %, numer;
123
(%o9) b
Note that although concat (1, 2) looks like a number, it is a string.
(%i10) concat (1, 2) + 3; (%o10) 12 + 3
Concatenates its arguments into a string. Unlike concat, the
arguments do not need to be atoms.
See also concat, simplode, string and eval_string.
For complex string conversions see also printf.
(%i1) sconcat ("xx[", 3, "]:", expand ((x+y)^3));
(%o1) xx[3]:y^3+3*x*y^2+3*x^2*y+x^3
Another purpose for sconcat is to convert arbitrary objects to strings.
(%i1) sconcat (x); (%o1) x
(%i2) stringp(%); (%o2) true
Converts expr to Maxima’s linear notation just as if it had been typed
in.
The return value of string is a string, and thus it cannot be used in a
computation.
See also concat, sconcat, simplode and
eval_string.
Default value: false
When stringdisp is true, strings are displayed enclosed in double
quote marks. Otherwise, quote marks are not displayed.
stringdisp is always true when displaying a function definition.
Examples:
(%i1) stringdisp: false$
(%i2) "This is an example string."; (%o2) This is an example string.
(%i3) foo () :=
print ("This is a string in a function definition.");
(%o3) foo() :=
print("This is a string in a function definition.")
(%i4) stringdisp: true$
(%i5) "This is an example string."; (%o5) "This is an example string."
