Function std.math.remainder.fmod
Calculates the remainder from the calculation x/y.
real fmod(
real x,
real y
) nothrow @nogc @trusted;
Returns
The value of x - i * y, where i is the number of times that y can be completely subtracted from x. The result has the same sign as x.
x | y | fmod(x, y) | invalid? |
---|---|---|---|
±0.0 | not 0.0 | ±0.0 | no |
±∞ | anything | NAN | yes |
anything | ±0.0 | NAN | yes |
!=±∞ | ±∞ | x | no |
Example
import std .math .operations : feqrel;
import std .math .traits : isIdentical, isNaN;
assert(isIdentical(fmod(0.0, 1.0), 0.0));
assert(fmod(5.0, 3.0) .feqrel(2.0) > 16);
assert(isNaN(fmod(5.0, 0.0)));
