About

Return correct number from a floating point number.

usage

let fp = require('yfp')
v = 0.1 + 0.2 // v: 0.30000000000000004
v = fp(0.1 + 0.2) // v: 0.3

eg2: Array

v = 0.1 + 0.2
ar = [v, v]
ar = fp(ar) // ar: [0.3, 0.3]

eg3: Object (recursive)

v = 0.1 + 0.2
ar = [v, v]
ob = {a:v, b:ar}
ob = fp(ob) // ob: { a: 0.3, b: [ 0.3, 0.3 ] }

options

function yfp(v, op = {}) {}

• op:
  • pc (Number): number of precision, default: 12 (max: 17)
  • toFixed/fixed/fix/fx (true false / 1 0): use toFixed instead of toPrecision, default: false
    • if toFixed is true: pc becomes decimals
  • type ('ceil|round|floor'): default:'floor'
