Hi.
I made a gadget in HC long (and I mean long) ago that did this for addition.
Here is the code:
function longAdd arg1,arg2
put 0 into carry
put abs(the length of arg1-the length of arg2) into numzeros
repeat numzeros
put "0" after leadingZeros
end repeat
if the length of arg1 >= the length of arg2 then
put the length of arg1 into index
put leadingZeros before arg2
else
put the length of arg2 into index
put leadingZeros before arg1
end if
repeat with y = index down to 1
put char y of arg1 + char y of arg2 + carry into temp
if char y of arg1 + char y of arg2 + carry > 9 then put 1 into carry else
put 0 into carry
put last char of temp before accum
end repeat
if carry = 1 then put "1" before accum
return accum
end longAdd

Subject: Integer-Calculation with 24 decimals?
Hello list,
I have to do a lot of calculations like 1234516789012345678901234 mod 97;
(always 24 decimals)
IntegerCalculation in LC with 24 decimals doesn´t work valide.
Does anyone of you know of an external function or a mathematical trick or …
Thank you in advance!
Richard.
