This optimization folds redundant integer-to-floating-point-to-integer conversions when the intermediate floating-point type can precisely represent all values of the final integer type. This improves code efficiency by eliminating unnecessary conversions, especially when the -fno-trapping-math option is enabled and the floating-point significand has sufficient precision.
