Yeah, the specific use case is I have a table of data, some
denominated in $ and some in ¢. It's generated by a PHP script. I need
to sort it on the client side in order of their values so I need to
divide the ¢ denominated ones by 100.

Both the $ and ¢ values have a decimal point.

Thanks for the reply!
