Hi All,


I'm in desparate need of a routine that calculates :

 X raised to the power of Y (like the pow(x,y) function in C++)

 where 0 < X < 1  (in a 0.16 fixed point notation)

 and Y = 1.00 to 1.50 (in a 1.7 fixed point notation)

for a PIC16C73B.

I have about 2K of code-space and about 5000 clock-cycles available. I
already have implemented 8*8, 16*16, 24*16, 16/16, 32/16, 32-bit shift
left and 32-bit shift right routines (all unsigned) routines that can
be used if necessary.

I can't find such a routine on the web and the microchip application
note doesn't bring me any further since they don't have the
implementation for the 16Cxx series and besides that, they use 32-bit
precision wich is too high for my application.

I'm looking forward to any reply.

Thanks!

Daniel...
