Integer-Calculation with 24 decimals?

[kee nethery]

For this, I'd do it "by hand". Treat the numbers as text in a field rather than digits and follow the same process you would if you were to do this on paper.

For modulo I'd start by making a list of multiples of 97 and start manually subtracting them.

for example,

1234516789012345678901234
-970000000000000000000000
264516789012345678901234

264516789012345678901234
-2 * 97000000000000000000000
=70516789012345678901234

rinse and repeat.

should be easy enough to do the subtraction and carry and such in code.

Eventually you end up with the modulo.

Easy enough to do the same thing with all the other math functions.
