- EXTMATH
-
- This is a library of C-callable assembler subroutines to do 64-bit
- unsigned math. The header file, extmath.h, typedef's an 8-byte data
- type, "extnum_t", which the functions all use. All the functions are
- two-operand operations, leaving the result in the second ("dest")
- argument, excepting ExtNeg(), which is a unary operation; ExtCmp(),
- which returns a signed integer as its result; and the two divide
- routines, ExtDiv() and ExtDivB(), which take four arguments (divisor,
- dividend, quotient, remainder).
