Hello all !!

For a project of mine, i am in need of some mathematics, particularly 16x16 multiplications.

I investigated the AN526 application note in the Microchip handbook, and used the DBL_MPYS.asm ( 16x16=32) with unsigned multiplication.

The results i got, though, were far from what i was expecting. I am multiplying a constant (d'328') by a variable (max: d'30000'), and when my
variable is > 199, i get strange results...

I dont have any idea what problem the Microchip routines may have.

Hints ? ideas ??  did someone ever use this routines ?

Thanks very much
