Remove suffixes from numbers

I'm looking for a way to remove suffixes "m", "k", "b", or "%" from numbers in Javascript.

I've successfully matched all digits which are followed by the letters I care about:

\b[\d\.]+[mkb%]\b

Given this set:

10.0 20.0k 30k 40k40 50m 60m6 m 70 m 80b80b 90%

I'd like to remove the suffixes from the 20, 30, 50, 90, and the trailing one from the 80. (the others don't have a word boundary after them)

I'm not clear on how to capture (and then remove) only the suffix portion of this. Little help?

Put the capture group around just the numeric part, not the whole thing.

/([\d.]+)[mkb]\b/

Use \b at front and also capture only the digit part. So that the captured chars would be back-referenced in the replacement part.

string.replace(/\b([\d\.]+)[mkb]\b/g, "$1")
