The code in this function is altered slightly to support floats
with 31-bits mantissas, thus the documentation below may be a
little bit inaccurate.
We now have to left shift the other littlenums by the same amount,
propagating the shifted bits into the more significant littlenums.
- To save a lot of unecessary shifting we only have to consider
+ To save a lot of unnecessary shifting we only have to consider
two or three littlenums, since the greatest number of mantissa
bits required is 24 + 1 rounding bit. While two littlenums
provide 32 bits of precision, the most significant littlenum
