R0 = dividend
R1 = divisor
R0 = quotient
R1 = modulo answer
081E4684 is another routine made by gamefreak that does modulo only.
A few other math routines:
081E460C: another division routine
081E3B9C: square root, calls swi 0x8
I've stumbled across a few others that I dont remember..
Thank you for your assistance.
