Huh? trans wasn't zero, it was 6.410000e-01, and the exponent was was
positive (1.747446e+00). Nothing seems particularly exceptional about this.
Also, pow doesn't literally return errno, that's just a global variable
you can look at. I think the only other return values are -HUGE_VAL and NaN.
What platform and toolchain are you using?
