Frac16 and Fract32 are representations of the values +1.0 to -1.0 so to convert them to an integer, just multipy them by the range you wish to represent.

For example: to have a range of -100 to 100, multiply the Fractxx value by 100.

Another way to look at this is to think in terms of the following equation:
 Fract = (integer value)/(maximum integer value)

So, multiplying a Fract16 by the maximum integer value yields the represented integer value.

If your range of integer values happens to be +32767 to -32768, then the Fract16 value is the corresponding integer value!!!

Subject: [motoroladsp] fractional number

Hello All,

I am having trouble working with fractions within my project.  I am
using a DSP56F826 chip with Codewarrior tools.

I am trying to create functions that will convert fractional data
(Frac16 and Frac32) into int and long int data.

Does anyone know how to do this either in C or in assembly?

Thanks,

Brad
