1. Big Fixed Math - v0.66.01 submitted
Arbitrary precision math library with power, root, and logarithm functions.
bigfixed.e is the only include file needed.
math.e is some of my prototype code. Proof of Concept.
Be sure to run the demo. The demo code is a little hard to read.
The demo was written as more of a sanity test and to help write the
documentation.
The documentation is far from completely, yet supplies all the
critical functions that are availalbe. plain_power() has not yet
been documented and is a very powerful function. It is useful
for calculating any base by a integer exponent.
Example: puts(1, plain_power("3.141 592 654","65,536"))
Note, commas and spaces are ignored in the number format.
Enjoy

Just out of curiosity, how long does it take to execute the above statement,
and on what kind of hardware?

AMD Athlon XP 2500+ (1.83Ghz)
include bigfixed.e -- Named bigfixedmath.e in the next release.
atom elapsed
sequence result
elapsed = time()
result = plain_power("3.141 592 654","65,536"))
elapsed = time() - elapsed
-- {length(result), seconds, minutes}
? {length(result), elapsed, elapsed/60}
Display: {32623, 156, 2.6}
I would have displayed the result, but it is a 32K file.
I then changed the exponent from 65,536 to 65,535 and
got these results.
Display: {32623, 201, 3.35}
65536 = power(2, 16) -- hence a nice binary number.
65535 is a worst case value.
PS: 3.14... will grow quickly. Using 65,535 takes longer.
A number much closer to 1 will generate nearly instant results.
