Clamp numbers to ranges taking into account the epsilon of the numbers at the end of the ranges. A range is string in Interval Notation such as "[2..4)" which means "between 2 (inclusive) and 4 (exclusive)."
npm install float-clamp
var floatClamp = ;
var randomClamper = floatClamp;//- Now randomClamper is a function that will clamp numbers to between 0 (inclusive)//- and 1 (exclusive)//- This is exactly the same range as values returned from Math.random()//=> 0//=> 0//=> 0.01//=> 0.9999999999999999
See below for clamp generators for other precision floating point numbers (and even an integer)
Shown above, generates clampers that calculates epsilons for double-precision floating point numbers. Every
Float64Array typed arrays.
Generates clampers that calculates epsilons for single-precision floating point numbers. In other words,
Float32Array typed arrays.
Integer clamping is easy, right?
Not so fast! All
Integers greater than 2^53 can not be represented exactly. This library takes that into account when used with very large exclsuive end-points and will clamp to the nearest valid integer to that exclusive end-point.
