Pull request overview

This PR reverts commit 99de5d4, which introduced SoftFloat changes that affected how floating-point literals are represented in C++ test expected output files. The revert restores the previous full-precision floating-point literal representation across multiple test expectation files.

Changes:

• Reverts floating-point literal representations from shortened format (e.g., 0.47438827, 1.0E-6) back to full-precision format (e.g., 0.4743882700000000008, 9.999999999999999547e-07)
• Restores line numbers in test expectation files that were removed during the original SoftFloat commit
• Affects four C++ test expected output files covering range analysis, control flow guards, and complex number builtins
