erand48()

Generate a pseudo-random double integer

Synopsis:

#include <stdlib.h>

double erand48( unsigned short int xsubi[3] );

Library:

libc

Description:

The erand48() function uses a linear congruential algorithm and 48-bit integer arithmetic to generate a positive double uniformly distributed over the interval [0.0, 1.0].

The xsubi array should contain the desired initial value; this makes erand48() thread-safe, and lets you start a sequence of random numbers at any known value.

Returns:

A pseudo-random double.

Classification:

Standard Unix
