i have this string extracted from a text file i'm writing a program to process:

test_freq = 1.0001;

and i have to extract the "1.0001"

i can't count on the whitspace being where it now is.

I would like to change this line of perl

$getTestFRQ =~ s/\D+//g;

so that instead of killing all non digit characters, it will kill all
non digit characters except for the period.

How do i do this?

thanks, ryan
