You don't. You use some other scripting language that knows what floats are.
Also, if you want your program to produce output from the sample data
set, you choose the boundary value so that some data is above and some
below. Example:
[EMAIL PROTECTED] nestor]$ cat data
111-11-1111| 24000.00
222-22-2222| 32560.15
333-33-3333| 45678.90
[EMAIL PROTECTED] nestor]$ cat script
#!/bin/awk -f
BEGIN{ FS="|"; limit=30000 }
{
if ($2 > l) { print $2, $1 }
}
[EMAIL PROTECTED] nestor]$ ./script data
32560.15 222-22-2222
45678.90 333-33-3333
