# NAME

MATH::simpleRNG - simple Random Number Generator

# SYNOPSIS

```  use Math::simpleRNG qw (sRNG);
\$random = sRNG('seed1','seed2');```

# DESCRIPTION

This function uses George Marsaglia's Multiply With Carry algorithm to produce uniformly distributed unsigned integers.

```  input:        seed1   [optional]
seed2   [optional]

return:       an unsigned random integer 1 -> 2^32 -1

Starting from a known set of non-zero seeds, the RNG
will return a repeating set of pseudo random numbers.

You may alter the pattern by periodically supplying
additional seed(s). If no seed is supplied or the seed
integer portion of the seed is zero, system time() is
used to seed the algorithm.```

Note: for smaller numbers, i.e. 3-4 digit

`  my \$num = sRNG int(sRNG()/5000000);`
