SPDiv

Divide two floating point numbers.

Accepts two floating point numbers and returns the quotient of the second argument divided by the first.

fnum1

floating point number.

fnum2

floating point number.

fnum3

floating point number.

Former autodocs did not document which register is the divisor and which the divident. The divisor is the first argument, in register D1, the divident is the second argument in D0. Note that the register allocation is identical to that of the IEEE math functions, but the order of the function arguments is exactly the inverse of IEEE. Former releases crashed with a divide-by-zero exception if the divisor was zero. This release returns the largest positive or negative number, depending on the signs of the arguments. Unfortunately, this also holds for the divison of 0 by 0.
