How to check nan in javascript. In javascript, nan is a number that is not a legal number. That makes this yet another valid way to. The number.isnan () method returns true if the value is.

The number.isnan method would only return true for number.isnan(0 / 0).all other examples would return false. To check whether the given number is nan or finite, we can use javascript methods. We recommend using number.isnan() over isnan() as it will only check if the given value would.

It's likely that tax or mug is a string and not a number. To tell if a value is nan, use number.isnan() or isnan() to most clearly determine whether a value is nan — or, since nan is the only value that compares unequal to itself, you can perform. To determine whether a number is nan, we can use the isnan ().

Is (nan, nan) // true object.is(nan, nan) will in fact return true, while we already know that nan === nan returns false. The isnan () method converts the value to a number before testing it. If this method returns false, then the number is a finite number else the.
