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.

Special Values
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);
