fmul |
Function (ROM Call 0xB8*) |
Floating point multiplication.
fmul returns the product of floating point arguments x and y.
This routine performs the same operation as the C '*'
operator applied to floating
point operands, but it is kept here to allow compatibility with older programs created before
TIGCC introduced floating point operators (i.e. before release 0.9 of TIGCC).
At the fundamental level, fmul is exactly the same routine as
bcdmul.
Note: fmul returns infinite result
in a case of overflow. See UNSIGNED_INF,
POSITIVE_INF and NEGATIVE_INF for
more details.
