X Title: Fix ldexp to prevent math range errors by YashSuthar983 · Pull Request #6216 · RustPython/RustPython

Description: Implemented IEEE 754-compliant handling for large numbers to avoid overflow and represent results using scientific notation. Fixes #5471 Summary by CodeRabbit Bug Fixes More accurate floating-point exponent scaling with precise IEEE‑754-aware handling and rounding. Corrected behavior for very large or very small exponents, including improved handling of subnormal values. Enhanced overflow and underflow detection with proper signed-zero returns where applicable. Maintains previous results for normal-range values while fixing edge-case math inaccuracies.
