this minimum-representable normal number or to negative
infinity.
The implementation of 3DNow! technology determines how
arithmetic overflow is handled—either properly signed
maximum- or minimum-representable normal numbers or
properly signed infinities. The processor generates properly
signed maximum- or minimum-representable normal numbers.
Infinities and NaNs are not supported as operands to 3DNow!
instructions.
The smallest representable normal number in magnitude for
this precision in hexadecimal has an exponent of 01h and a
significand of 000000h, with a numerical value of 2
–126
.
Accordingly, all results below this minimum representable
value in magnitude are held to zero. Table 1 shows the
exponent ranges supported by the 3DNow! technology.
Like MMX instructions, 3DNow! instructions do not generate
numeric exceptions nor do they set any status flags. It is the
user’s responsibility to ensure that in-range data is provided to
3DNow! instructions and that all computations remain within
valid ranges (or are held as expected).
