Math.max and Math.min NaN on undefined entry

javascript, jquery

Solution

I assume the `undefined` is actually some variable.

You can substitute `-Infinity` for any `NaN` value to ensure a number.

var foo;

Math.max(5, 10, isNaN(foo) ? -Infinity : foo); // returns 10

Same concept can be used on `Math.min`, but with `Infinity`:

var foo;

Math.min(5, 10, isNaN(foo) ? Infinity : foo); // returns 5

Problem

When passing values to the `Math.max` or `Math.min` function in JavaScript, they return the highest and lowest values from the input respectively. However, if a piece of data that is undefined is entered, e.g. ``` Math.max(5,10,undefined); ``` The result returned is `NaN`. Is there a simply way to fix this using JS/jQuery?
