    ratio - ℚ in JS build status

    Sometimes you want to handle a ratio as its own entity. Yeah, you could downcast to decimal (though on floating point that's really a crime), or encode it as a string, but neither of those really cuts it.

    So why not npm install ratio?

    var ratio = require('ratio')
      , half = ratio(4,8)
     
    half === 0.5 // true 
    half.toString() === '1/2' // true 
    ratio(0.02).toSring() === '1/50'

    features

    • flexible instantiation:
      • from numerator and denominator
      • from string
      • from decimal number
    • nice rendering
      • valueOf() returns numeric form
      • toString() renders fractional form
    • automatically reduces fractions on creation
    • fraction arithmetic
      • addition with r.plus(x)
      • subtraction with r.minus(x)
      • multiplication with r.times(x)
      • division with r.div(x)
      • reciprocal with r.reciprocal()
      • negative with r.neg()
