Paolo, the simplification you made are great!
But you just swapped the lowBit test...
Example:
self assert: ((1 bitShift: 53+100) + (1 bitShift: 100) + 1) asFloatD
truncated lowBit = 102.
Number of truncated bits is 101.
Carry is 1.
Truncated mantissa candidate is even (1 bitShift: 52).
But there are other trailing bits behind the carry (self lowBit <
nTruncatedBits), so the truncated part > 0.5 ulp, so the mantissa must
be rounded upper.
Please correct.
Cheers
