# Whether precise division should be used in calculation. Most cheap
# microcontrollers do not implement division in hardware, so enabling this will
# lead to inclusion of code implementing software division. This may increase
# the firmware size severely. If left disabled approximate software division by
# a constant will be used instead, which has a 1% error but takes only a few
# processor instructions. This approximate division works as follows. First,
# (2^24 / divisor) is precalculated before compilation. This is multiplied by
# the dividend in runtime, all in 32-bit values. Finally, the result is
# right-shifted by 16 bits, resulting in (256 * dividend / divisor) with 1%
# accuracy.
# 256 * dividend / divisor =~= [(2^24 / divisor) * dividend] / 2^16.
