Re: ICONS...(DEAD HORSE I KNOW)
# If you want to round to the nearest integer:
#
# function round( atom number )
# return floor( number + 0.5 )
# end function
Although we all know that float() is horribly slow, in fact slower than
sqrt(). In a thread a long time ago this was discussed, and Rob explained that
Intel have a round() and sqrt() instruction on the chip but floor() has to be
done in software.
What I cannot remember ever being told was why, if this is the case, we have
floor() and do not have round(). Also why we could not have both, and why
floor() cannot be hardcoded to be intel:machine_round(x-.5) [pseudocode]
Rob ?
