please need help with dllstructs and arithmetics

[jennico]

hi there,

i need to operate with large integers. example:

Mod(2121233235543365*2121233235543365,5232225434356058)

the result must be smaller than 5232225434356058, but autoit cannot handle the intermediate product.

so i tried it with dllcalls :

Dim $tStruct = DllStructCreate("double");or uint64 or int64 ?
DllStructSetData($tStruct, 1, DllStructGetData($tStruct, 1) +2121233235543365)
DllStructSetData($tStruct, 1, DllStructGetData($tStruct, 1) *2121233235543365)
DllStructSetData($tStruct, 1, DllStructGetData($tStruct, 1) /5232225434356058)
MsgBox(0,"result=",DllStructGetData($tStruct, 1))

the result (an integer) is correct so far. but i wanted a modulo operation.

can anyone tell me the equivalent so that i can get the remainder and not the integer part of the division ?

thx j.

Have you tried this on a 64bit OS, with the 64bit compile option of AutoIt? And is your sig really saying you are running version 3.2.8.1 of AutoIt?
