Computes the absolute value of a floating-point number
x
.
Synopsis
#include <math.h>
double fabs(double x);
float fabsf(float x);
Returns
The absolute value of x.
Example
double y=6.23;
double x;
x=fabs(y);
floor, floorf
Computes the largest integer not greater than x.
Synopsis
#include <math.h>
double floor(double x);
float floorf(float x);
Returns
The largest integer not greater than x, expressed as a
double
for
floor
and expressed as
a
float
for
floorf
.
Example
double y=6.23;
double x;
x=floor(y);
fmod, fmodf
Computes the floating-point remainder of
x
/
y
. If the quotient of
x
/
y
cannot be represented,
the behavior is undefined.
