Function std.math.algebraic.fabs
Returns |x|
real fabs
(
real x
) pure nothrow @nogc @safe;
double fabs
(
double x
) pure nothrow @nogc @safe;
float fabs
(
float x
) pure nothrow @nogc @safe;
x | fabs(x) |
---|---|
±0.0 | +0.0 |
±∞ | +∞ |
Example
import std .math .traits : isIdentical;
assert(isIdentical(fabs(0.0f), 0.0f));
assert(isIdentical(fabs(-0.0f), 0.0f));
writeln(fabs(-10.0f)); // 10.0f
assert(isIdentical(fabs(0.0), 0.0));
assert(isIdentical(fabs(-0.0), 0.0));
writeln(fabs(-10.0)); // 10.0
assert(isIdentical(fabs(0.0L), 0.0L));
assert(isIdentical(fabs(-0.0L), 0.0L));
writeln(fabs(-10.0L)); // 10.0L
