Divfract32 Lib function

Question asked by dspgeek on Sep 29, 2009

Hi Analog Devices,

 

The divfract32 from Analog Devices library gives 1.31/1.31==>1.31 result.

 

But the precondition makes me a bit unhappy. "the numerator is always less than the denominator" I can understand this.

 

But how to circumvent this problem? Also is it possible to take inverse of a 1.31 number and multiply?

 

how would the inverse look like? 1/1.31 is not allowed in fractional math or?

 

 

Please let me know more about it. Is there any application note on this topic?

 

Regards
