NAME
- SPSub
-
Subtract two floating point numbers.
SYNOPSIS
fnum3 = SPSub(fnum1, fnum2)
D0 D1 D0
float SPSub(float fnum1, float fnum2);
D0 D1 D0
float SPSub(float fnum1, float fnum2);
FUNCTION
Accepts two floating point numbers and subtracts the first argument from the second.
INPUTS
- fnum1
-
floating point number.
- fnum2
-
floating point number.
RESULT
- fnum3
-
floating point number.
BUGS
Former attempts to document this function did not make clear which argument is subtracted from which.
Note that the order of subtraction is identical to the order of subtraction of IEEE math if looked at the register allocation. but the *inverse* of the IEEE model if looked at the position of the function arguments, i.e. IEEE math subtracts the second argument from the first.
