Siddhesh Poyarekar 5739f705ee Use integral constants 
The compiler is smart enough to convert those into double for powerpc,
but if we put them as doubles, it adds overhead by performing those
operations in floating point mode.

Siddhesh Poyarekar e375e83d17 Removed commented code 2013-03-26 20:14:18 +05:30
Siddhesh Poyarekar 6f2e90e78f Make mantissa type of mp_no configurable 
The mantissa of mp_no is intended to take only integral values.  This
is a relatively good choice for powerpc due to its 4 fpus, but not for
other architectures, which suffer due to this choice.  This change
makes the default mantissa a long integer and allows powerpc to
override it.  Additionally, some operations have been optimized for
integer manipulation, resulting in a significant improvement in
performance.

Siddhesh Poyarekar 1e3803454e Revert configurable mantissa patch 
Reverts d22ca8cdfb

since it is severely broken on 32-bit.
 2013-03-15 23:18:51 +05:30
Siddhesh Poyarekar d22ca8cdfb Make mantissa type configurable 
This allows the default mantissa to be integral, with powerpc
overriding it to take advantage of its FPUs.

Siddhesh Poyarekar 45f058844c Another tweak to the multiplication algorithm 
Reduce the formula to calculate mantissa so that we reduce the net
number of multiplications performed.

Siddhesh Poyarekar e69804d14e Use long wherever possible in mpa.c 
Using long throughout like powerpc does is beneficial since it reduces
the need to switch to 32-bit instructions.  It gives a very minor
performance improvement.
