math: Properly cast X_TLOSS to float [BZ #28713]
Add #define AS_FLOAT_CONSTANT_1(x) x##f #define AS_FLOAT_CONSTANT(x) AS_FLOAT_CONSTANT_1(x) to cast X_TLOSS to float at compile-time to fix: FAIL: math/test-float-j0 FAIL: math/test-float-jn FAIL: math/test-float-y0 FAIL: math/test-float-y1 FAIL: math/test-float-yn FAIL: math/test-float32-j0 FAIL: math/test-float32-jn FAIL: math/test-float32-y0 FAIL: math/test-float32-y1 FAIL: math/test-float32-yn when compiling with GCC 12.
