Quick Maths

A chain-able, small, quick maths+utils lib qm(4).plus(1).dividedby(2).fin() -> 2.5

Usage (coming to an npm repo near you soon)

$ yarn add quick-maths

const qm = require('quick-maths');
// or
import qm from 'quick-maths';

qm(1).times(-5).dividedby(3).minus(1).plus(5).times(2).fin(2)
//=> 4.66

qm(5).times(-5).fin()
//=> -25

qm(10).roughly(10.3)
//=> true

qm(10).equals(1850)
//=> false

.times(input)

input

Type: int/float

Value that the current number will be multiplied by.

.dividedby(input)

input

Type: int/float

Value that the current number will be divided by.

.equals(input)

input, returns boolean

Type: int/float
