matical quotient, and the magnitude of the quotient is the largest integer less than the mag-
nitude of the mathematical quotient.
Synopsis
#include
div_t div(int numer, int denom);
Returns
A structure of type div_t, comprising both the quotient and the remainder. The structure
contains the following members, in either order:
int quot;
/* quotient */
int rem;
/* remainder */
Example
int x=25;
int y=3;
div_t t;
int q;
int r;
t=div (x,y);
q=t.quot;
r=t.rem;
exp, expf
Computes the exponential function of
x
. A range error occurs if the magnitude of
x
is too
large.
Synopsis
#include
double exp(double x);
float expf(float x);
Returns
The exponential value.
Example
double y=.1234;
double x;
x=exp(y);
