Hi,How can I convert the decimal fraction to the mantissa format (IEEE). The MegaWizard function demands the decimal number in binary form (3 = 0011, for example). So how can I convert 0.3 to mantissa without multipling on 10 or 100 etc? Other way, if i starting to multiply so i don't net to use mantissa, am i wright? My final target is to apply the next math function y = 0.201x + 7.899 I supplying the "x" values. Can anybody help me with this question, please?
the input is an integer, which will always be binary. But in fixed point, the integer and fractional parts are just normal integers offset by 2^n. Have a read up on fixed point number formats.Are you sure you want to use flooating point?
