Methods

randomNumber(flooropt, nullable, ceilingopt, nullable, floatopt, nullable, precisionopt, nullable) → {Number}

Special form of Math.random, returning a value in a defined range, where floor and ceiling are included in the range.

By default, this method return an integer, but by setting "float" to true and optionally providing a float precision you can also work with floating point numbers.

Parameters:
Name Type Attributes Default Description
floor Number <optional>
<nullable>
 0

the lower end of random range, can either be integer or float
ceiling Number <optional>
<nullable>
 10

the upper end of random range, can either be integer or float
float Boolean <optional>
<nullable>
 false

define if we are working with floating point numbers
precision Number <optional>
<nullable>
 2

if we are working with floats, what precision are we working with, considering floor, ceiling and result?
