I have a string, and I need to extract decimal number upto two precision using Regex function in Javascript.

or example, if I have string "RequestedAmount-12.20", I need to get the output as 12.20 and not 12.2. The regex I am using, gives me 12.2.

Here is the Regex I used.

str="RequestedAmout-12.20"
requestedamt = Number( str.replace( /[^0-9\.]+/g, "" ) );

I should get 12.20

The number `12.2` is exactly the same as the number `12.20`. – Pointy Aug 29 '19 at 20:37
See https://stackoverflow.com/a/4691032/3832970. Use `String#match()` to get the value. – Wiktor Stribiżew Aug 29 '19 at 20:38
