I think that it should, after all it is basic floating point, and if I
remember the actual powers are stored as an array of const doubles of alt
least 11 double locations! Also check out the const DBL_MAX_10_EXP, as this
will also effect the size of the memory used.
If you have a look at the code used, you will see that there is also a const
table defined in:- double exp (double), and that the actual function pow
also uses a multiply routine. You will find the code used in EXP.C. Without
knowing much about the code you are using, I think that the result of 500
bytes is very good indeed.
