Function randomInt #

Return a random integer number between min and max using a uniform distribution.

Syntax #

math.randomInt()                // generate a random integer between 0 and 1
math.randomInt(max)             // generate a random integer between 0 and max
math.randomInt(min, max)        // generate a random integer between min and max
math.randomInt(size)            // generate a matrix with random integer between 0 and 1
math.randomInt(size, max)       // generate a matrix with random integer between 0 and max
math.randomInt(size, min, max)  // generate a matrix with random integer between min and max

Parameters #

Parameter	Type	Description
size	Number	If provided, an array with size number of random values is returned
min	Number	Minimum boundary for the random value
max	Number	Maximum boundary for the random value

Returns #

Type	Description
Number | Array | Matrix	A random integer value

Examples #
