Can you use written numbers with whole numbers to return a total value?

While its easy to think that the user will enter the numbers we are asking for as whole numbers or decimals what if they type the word out? As it is now it will return only NaN but for real world use if a user got this error it would be confusing and frustrating. Is there anyway to assign each number with a its value as a word? Would you have to do this for every number? Or is there some kind of shorthand or maybe formula you can apply to make the code read numbers written as words as numbers?

Better to have some user side validation which clearly tells the user that the value entered needs to be a number should they try to type in text.

I agree with Daniel on this one. It is better to keep things simple by using client side validation than to use up a bunch of time writing an algorithm that makes it possible to accept numbers as words and integers. https://en.wikipedia.org/wiki/KISS_principle
