If a number has .00 how can you remove it?

Question

I've been looking around for this answer and there are some alternatives. Unfortunately, none of them makes sense to me.

I am working on an e-commerce website where they the product price automatically uploads '.00' if its a whole number. We have some products that will display the decimals where used (i.e £13.50) but we just want all instances of .00 removed from pricing.

Do let me know if anyone needs any more information on this. I know the pricing comes from many parts of the website and not just one particular class.

Answer 1

If you only want to remove the .00 if it's the end of a string, then you may do

str = str.replace(/\.00$/,'');

If your .00 may not be at the end of your string, for example it's "10.00 $ and 24.00€", then do

str = str.replace(/\.00([^\d])/g,'$1');

What follows here is more a comment :

Most often, number formatting involve many other requirements, we can't guess what are yours.

Here's for example the test set of one of my number formatting functions :

//   formatFloat(100.0)     => "100"
//   formatFloat(100.0, 12) => "100"
//   formatFloat(100.1)    => "100.1"
//   formatFloat(100.1, 0) => "100"
//   formatFloat(100.7, 0) => "101"
//   formatFloat(.0434) => "0.043"
//   formatFloat(1.999999) => "2"
//   formatFloat(.0000047)     => "0"
//   formatFloat(.0000047, 6)  => "0.000005"
//   formatFloat(.0000047, 12) => "0.0000047"
//   formatFloat(undefined) => ""
//   formatFloat(NaN) => ""

So if you're not happy with the solution I gave you, please take the time to define your complete requirement.
