Random Number Generation Functions(3.1)

Use the functions below to generate random integer values.

randomInt

Returns a pseudorandom, uniformly distributed int value from a random number generator initiated at workflow start.

The values returned will be pseudorandomly generated and returned. All 2^31 possible int  values are produced  with (approximately) equal probability.

This function uses the standard Java Random class. Refer to JDK documentation for exact details on the algorithm used for generating pseudorandom values.

int randomInt(int bound)
ParameterDescription

bound

The upper bound (exclusive).  Must be positive.

Returns

A random integer in the range 0 to bound-1

randomLong

Returns a pseudorandom, uniformly distributed long value from a random number generator initiated at workflow start.

The values returned will be pseudorandomly generated and returned. The algorithm uses a seed with only 48 bits, which means that not all possible long values will be returned.

This function uses the standard Java Random class. Refer to JDK documentation for exact details on the algorithm used for generating pseudorandom values.

long randomLong()
ParameterDescription

Returns

A random long
