确保股息大于除数的功能？

Question

Hey just curious is there a function that you can use to divide in "the right order", so that the dividend is always the larger number? Currently I do this

x=5
y=10
z=0

if x>y{
z = x/y
}else{
z = y/x
}

I was just wondering if there was a function I could use to do this in one line, like

MakeSureDividendBigger(x/y)

type thing.

Thanks

Answer 1

Javascript:

var z = Math.max(x, y) / Math.min(x, y);

Or a function:

function divideNice(x, y) {
    return Math.max(x, y) / Math.min(x, y);
}

var z = divideNice(x, y);

PHP:

$z = max($x, $y) / min($x, $y)

Answer 2

I doubt there is a special function for this, but possible one line solution is to use ternary conditional operator :

$z = $x > $y ? $x / $y : $y / $x;    // PHP

var z = x > y ? x / y : y / x;       // JavaScript

You can use Math.max and Math.min .

Math.max(x,y) / Math.min(x,y)

• Math.max
• Math.min

Or in Mozilla (Firefox) you can easily do a swap.

if(x < y)
   [x,y] = [y,x]

x/y

This is called destructuring assignment .
