@fav/arith.divide

Calculates an accurate quotient of two numbers.

"fav" is an abbreviation of "favorite" and also the acronym of "for all versions". This package is intended to support all Node.js versions and many browsers as possible. At least, this package supports Node.js >= v0.10 and major Web browsers: Chrome, Firefox, IE11, Edge, Vivaldi and Safari.

Install

To install from npm:

$ npm install --save @fav/arith.number @fav/arith.divide

NOTE: npm < 2.7.0 does not support scoped package, but old version Node.js supports it. So when you use such older npm, you should download this package from github.com, and move it in node_modules/@fav/arith.divide/ directory manually.

Usage

For Node.js:

var ArithNumber = require('@fav/arith.number');
var divide = require('@fav/arith.divide');

var num1 = ArithNumber.of(1.23) // => { numerator: 123, denominator: 1, exponent: -2 }

var num2 = ArithNumber.of('0.4') // => { numerator: 4, denominator: 1, exponent: -1 }

1.23 / 0.4 // => 3.0749999999999997

var num3 = divide(num1, num2) // => { numerator: 3075, denominator: 1, exponent: -3 }
num3.toApproximateString() // => '3.075'

For Web browsers:

<script src="fav.arith.number.min.js"></script>
<script>
var ArithNumber = fav.arith.number;
var divide = fav.arith.divide;

var num1 = ArithNumber.of(1.23) // => { numerator: 123, denominator: 1, exponent: -2 }

var num2 = ArithNumber.of('0.4') // => { numerator: 4, denominator: 1, exponent: -1 }

1.23 / 0.4 // => 3.0749999999999997

var num3 = divide(num1, num2) // => { numerator: 3075, denominator: 1, exponent: -3 }
num3.toApproximateString() // => '3.075'
</script>

API

divide(arithNum1, arithNum2) : ArithNumber

Divides arithNum1 and arithNum2 and create a new ArithNumber object which has the quotient of these two numbers.

Parameters:

| Parameter | Type | Description | |:-------------|:-----------:|:---------------------------------------| | arithNum1 | ArithNumber | An ArithNumber object to be divided. | | arithNum2 | ArithNumber | An ArithNumber object to be divided. |

Returns:

The quotient of two values of ArithNumber objects.

Type: ArithNumber
