Function Documentation

float ExpRand

(

)

A random number generator that generates an exponentially distributed pseudorandom floating point number between 0 and 1.

Returns

An exponentially distributed random number > 0 and < 1.

float ExpRand

(

float

omega

)

A random number generator that generates an exponentially distributed pseudorandom floating point number between 0 and 1 with the tail of the distribution artificially lifted up.

Parameters

omega

The tail multiplier, which controls how low the tails of the distribution can be.

Returns

An exponentially distributed random number > 0 and < 1.

float UniformRand

(

)

A random number generator that generates a uniformly distributed pseudorandom floating point number between 0 and 1.

Returns

A uniformly distributed random number > 0 and < 1.
