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.
