labs
Computes the absolute value of a long int j.
Synopsis
#include <stdlib.h>
long labs(long j);
Example
long i=-193250;
long j;
j=labs(i);
ldexp
Multiplies a floating-point number by an integral power of 2. A range error can occur.
Synopsis
#include <math.h>
double ldexp(double x, int exp);
Returns
The value of x times 2 raised to the power of exp.
Example
double x=1.235;
int exp=2;
double y;
y=ldexp(x,exp);
ldiv
Computes the quotient and remainder of the division of the numerator numer by the
denominator denom . If the division is inexact, the sign of the quotient is that of the
mathematical quotient, and the magnitude of the quotient is the largest integer less than
the magnitude of the mathematical quotient.
Synopsis
#include <stdlib.h>
ldiv_t ldiv(long numer, long denom);
Example
long x=25000;
long y=300;
