modff
Description:
Include:
Prototype:
Arguments:
Return Value:
Remarks:
Example:
Splits a single precision floating-point value into fractional and integer
parts.
<math.h>
float modff(float x, float *pint);
x
pint
Returns the signed fractional part and pint points to the integer part.
The absolute value of the fractional part is in the range of 0 (inclusive)
to 1 (exclusive). No domain or range error will occur.
#include <math.h>
#include <stdio.h> /* for printf */
int main(void)
{
}
Output:
For 0.707000 the fraction is 0.707000
For -15.212100 the fraction is -0.212100
float x,y,n;
x = 0.707F;
y = modff (x, &n);
printf("For %f the fraction is %f\n ", x, y);
printf("
x = -15.2121F;
y = modff (x, &n);
printf("For %f the fraction is %f\n ", x, y);
printf("
and the integer is 0
and the integer is -15
single precision floating-point value
pointer to stored integer part
and the integer is %0.f\n\n", n);
and the integer is %0.f\n\n", n);
