Function Documentation

void randomReset

(

)

Resets the random seed using the current time so, in principle, the reset is hard to predict.

Definition at line 18 of file random.c.

void randomSet

(

unsigned int

seed

)

Sets the random to the given value. This is used to get repetitive sequences of random numbers in order to debug mainly.

Parameters:

seed

The new random seed.

double randomDouble

(

)

[inline]

Returns a random number in the [0,1] interval selected with a uniform distribution.

Returns:

A random double in [0,1].

)

Returns a random number following a normal distribution with mean 0 and standard deviation 1.

Returns:

A random double.
