Try to use more deterministic floating-point operations. Apparently, 2.2 > 2.2 wrongly holds on many platforms, but not ppc64le on the compiler used on Red Had Enterprise Linux 8. The reason could be an infinite binary presentation: 2.2 = 0b10.001100110011… With t1_f = 2.5 = 0b10.1, t1_f > 2.5 would no longer hold on AMD64. Let us replace the 2.2 with 2.5 and compare t1_f >= 2.5 in order to get more consistent results across all platforms.
