Function random

Produces a random number between the inclusive lower and upper bounds. If only one argument is provided a number between 0 and the given number is returned. If floating is true, or either lower or upper are floats, a floating-point number is returned instead of an integer.

Note: JavaScript follows the IEEE-754 standard for resolving floating-point values which can produce unexpected results.

random(0, 5)
// => an integer between 0 and 5

random(5)
// => also an integer between 0 and 5

random(5, true)
// => a floating-point number between 0 and 5

random(1.2, 5.2)
// => a floating-point number between 1.2 and 5.2
