There is no program only an example. Nothing for free - show us what you have done and we will comment and help you out but you have to do something yourself. It is really pretty easy.

Well, I told my teacher about this function but he said that is too easy.
I read about floating number.
Floating number has:
1. sign
2. exponent
3. mantisa

Anyone know how to add or multiply two another (sign exponent mantisa)?

There is also 32 bit and 64 bit - Omron PLCs have the floating point instructions available in all the latest PLCs. Check the manual.Check +F and *F.
