Functions¶

seed¶

1

public p seed(unsigned long seedValue)

Seed the pseudo-random number generator. Note: A seed of 0 is replaced by a fixed non-zero constant, as the generator cannot escape the all-zero state.

Parameters

randULong¶

1

public f<unsigned long> randULong()

Generate a raw pseudo-random unsigned long, uniformly distributed over the whole 64-bit range.

Returns: unsigned long — Random unsigned long

randInt¶

1

public f<int> randInt(int min, int max)

Generates a random integer between min and max Note: Both min and max are inclusive: [min, max] Note: If min > max, the function always returns max

Parameters

Returns: int — Random number

randDouble¶

1

public f<double> randDouble()

Generate a random double, uniformly distributed in the half-open interval [0, 1).

Returns: double — Random double in [0, 1)

randDouble¶

1

public f<double> randDouble(double min, double max)

Generate a random double, uniformly distributed in the half-open interval [min, max). Note: If min > max, the function always returns max

Parameters

Returns: double — Random double in [min, max)

randBool¶

1

public f<bool> randBool()

Generate a random boolean value with equal probability for true and false.

Returns: bool — Random boolean

randGaussian¶

1

public f<double> randGaussian(double mean, double stdDev)

Generate a normally distributed random double with the given mean and standard deviation, using the Box-Muller transform.

Parameters

Returns: double — Normally distributed random double
