5) count_leading_zeros(count, x) counts the number of zero-bits from the
- msb to the first non-zero bit in the UWtype X. This is the number of
+ msb to the first nonzero bit in the UWtype X. This is the number of
steps X needs to be shifted left to set the msb. Undefined for X == 0,
unless the symbol COUNT_LEADING_ZEROS_0 is defined to some value.
