Hi,

How do I exactly use the fpu after enabled it ?
How do I for example put 5.5 into it and add 3.25 for example
Dooes my software have to do the conversion and just let the fpu cdo the addition , or is the fpu also capable of doing the conversion from 5.5 integer to float ?
Is there any good reference on this subject ?

Thanks!

Ronny Suy
