In most mathematics, there's no real need for distinction between the fractional portion and the whole portion, especially given that the whole thing can be expressed as a fraction (18/7ths), as a real number, or as a mix of integers and fractions (2 and 4/7ths).

When you get into programming or engineering, or some other derivative, you have definite uses for the separation; but the quotient is really the whole thing, integer and fraction, however you choose to represent that.

We can use simple mathematics to get answer using only <code>/</code> &amp; <code>%</code> operator.

Consider 'num1' as first value &amp; 'num2' as second value. Then :

<pre><code>var Quotient = (num1 - (num1 % num2)) / num2;

var FloatingPoint = (num1 % num2) / num2;
</code></pre>

2 is the quotient (or integer part of the result), 4 is the remainder, and 4/7 is the floating point part of the result, which the OP is requesting.

On my calculator when I do 18/7 I get 2.5714285714285714285714285714286.
From my super limited Math skills 2 is the quotient and .5714285714285714285714285714286 is the remainder.

How can I model this in JavaScript?

Thanks!

在我的计算器上，当我做18/7时，我得到的是2.57142857142814281414285714286。根据我有限的数学技能，2是商，.5714285714285714285714285714286是余数。如何在JavaScript中对此进行建模？谢谢!
