Random generator for float values.


The RandomFloat class allows you to generate random float values.

Static methods


Generates a float in the range [‘min’, ‘max’]. If ‘max’ is omitted, then the range will be set to [0, ‘min’].

public static nextFloat(min: number, max: number = null): number

  • min: number - (minimum value of the float that will be generated.
    If ‘max’ is omitted, then ‘max’ is set to ‘min’ and ‘min’ is set to 0.
  • max: number - (optional) maximum value of the float that will be generated. Defaults to ‘min’ if omitted.
  • returns: number - generated random float value.


Updates (drifts) a float value within specified range.

public static updateFloat(value: number, range: number = null): number

  • value: number - float value to drift.
  • range: number - (optional) range. Default: 10% of the value.
  • returns: number - updated float value.


let value1 = RandomFloat.nextFloat(5, 10);     // Possible result: 7.3
let value2 = RandomFloat.nextFloat(10);        // Possible result: 3.7
let value3 = RandomFloat.updateFloat(10, 3);   // Possible result: 9.2
