fit-to-range

Fit a number to a given range

Fits a number to a given range. The (simple) algorithm is:

1. If number is equal or lower than lower bound - return lower bound.
2. If number is equal or higher than upper bound - return upper bound.
3. Return number.

A valid number is any regular integer/float, +-Infinity. NaN is invalid.

Installation

npm install --save fit-to-range

Usage

fitToRange(num, lowerBound, upperBound)

var fitToRange = require('fit-to-range');
 
var fitted;
fitted = fitToRange(5, 10, 20);
// => 10
 
fitted = fitToRange(25, 10, 20);
// => 20
 
fitted = fitToRange(0, -1, 1);
// => 0
 
fitted = fitToRange(1, -Infinity, 0);
// => 0
