Suppress the decimal point, keep the decimal numbers

I've used the "replace". This gets rid of the period and the comma.
replace(replace(totext({PAYMASTR.NET_PAY_AMT}),".",""),",","")

Try something like this toText((ER_Match)*100,"0")

Excuse me if I misinterpreted but I think what youre asking is you dont want to show the decimal place (precision of 0) but you dont want it round? If so:

In Crystal right click the field
Select Formatt Field
Go to the Numbers Tab
Click Customize
Set the Decimals Drop Down to 1
Set the Rounding Drop Down to 0.01

I usually do these types of things in the SQL statement command.
For example - one of the files I had to create needed the rate of pay to be formated with no decimal point and it needed to be a number not text.
The way I accomplished this was with the following;

TO_NUMBER(REGEXP_REPLACE(TO_CHAR(e.pay_rate,'999.9999'),'\D',''),9999999)

This removes the decimal and ensures the format is numeric and the full length required.

However if you want to do it within Crystal then the suggenstion John gave would work also and if you want to take his and have it create a numeric field you could do

ToNumber(ToText({PAY_RATE}*10000,"0"))

Both toText({ER_Match)*100,"0")
and toNumber(toText({ER_Match)*100,"0"))
worked - thank you Gentlemen!
