Function std.math.remainder.modf
Breaks x into an integral part and a fractional part, each of which has the same sign as x. The integral part is stored in i.
real modf
(
real x,
ref real i
) nothrow @nogc @trusted;
Returns
The fractional part of x.
x | i (on input) | modf(x, i) | i (on return) |
---|---|---|---|
±∞ | anything | ±0.0 | ±∞ |
Example
import std .math .operations : feqrel;
real frac;
real intpart;
frac = modf(3.14159, intpart);
assert(intpart .feqrel(3.0) > 16);
assert(frac .feqrel(0.14159) > 16);
