Hi, I need really help now - my nephew has a problem in school to do a precise calculation of a math term:

result = rho . h . delta r^4 . delta phi . n . Sum [(2*j-1)/2 ]^3 j:1...n

So I wrote (quick and dirty and SLOOOW!) procedures for "+", "-" and "*" which do calculations of numbers stored into strings...

The routines ignore signs (should be changed in the future, for now the formula above it is not important) and they are all very slow.

So my question - has anyone done something like this already for Purebasic (V4)? Maybe in assembler? I need to speed up the program very urgently...

you could use GMP, compiled dll's are available at ftp://deltatrinity.dyndns.org/ gmp-4.2 is latest version.
also get the import lib ->libgmp-3.lib

get the gmp manual http://www.swox.com/gmp/
here's an example of use, donn't have time to comment, got to go work.

Thanks, jack...

I've tested the routines, which are about 10 to 20 times faster than my brute force methode with strings (compared with the math term I had to solve)...

So, the only possibility to beat this routines would be to do write assembler routines for calculating with strings, maybe someone will try to do that?! :roll:

Line 50 of the above GMP example code gives me "String return type can't be used in Import/EndImport section." Obviously some things have changes since that code was posted. Can anyone tell me how to do this correctly using PB 5.41?

EDIT: It is this line here:

LIB files are not easy to find.

The files I found so far either give 'corrupt' or "invalid machine type". I'll keep trying.

Posted: **Thu Feb 04, 2016 8:58 pm**

There is another version I just found here: http://www.purebasic.fr/english/viewtop ... 33#p458533

It uses OpenLibrary instead of Import and this seems to work with the same library files.

Thanks.
