FDIV FSQRT Rounding Mode Calculation Mismatches

FDIV and FSQRT rounding mode calculation mismatches found when comparing the results from FPnew to a RocketChip RISCV IMAF processor.

I have attached a few examples of calculation mismatches found: FDIV FSQRT Rounding Mode Calculation Mismatches .xlsx

Note: I have added the solution from issue #47 since it fixed rounding mode issues found when testing against the RISCV Compliance tests, and I have found there are less rounding mode issues detected with it included.

Can you comment on my findings?
