Logix 500 math instruction with Decimal Point

Hi my problem may have a simple solution but i cant work it out.

I need to use the Divide function but it wont let me use a decimal point in either Source A or Source B. Is there a way to use a decimal point in Logix 500 Math instructions? Im using an AB Micrologix 1400 PLC.

Can you only use math instructions with whole numbers? is there a way around this?

Thanks

James
