# plrandd(3plplot)

Random number generator returning a real random number in the range \[0,1\]

## NAME

**plrandd** - Random number generator returning a real random number in the range \[0,1\]

## SYNOPSIS

**plrandd**()

## DESCRIPTION

Random number generator returning a real random number in the range \[0,1\]. The generator is based on the Mersenne Twister. Most languages / compilers provide their own random number generator, and so this is provided purely for convenience and to give a consistent random number generator across all languages supported by PLplot. This is particularly useful for comparing results from the test suite of examples.

Redacted form: **plrandd()**

This function is used in examples 17 and 21.
