Optimized Stack Operations

[Paul Dale]

The multiplication and division using CMULT will pull in the maths routines.

Better would be to decompose and recompose the double into its mantissa and exponent using a union or byte operations. A shift by 20 bits will give the six digits you're after.

Alternatively, store your "reals" as pairs of integers:

Code:

struct real_st {
    long int mantissa;
    short int exponent;
};

and use integer operations exclusively.
