Issue #11582 has been updated by ngoto (Naohisa Goto). Status changed from Third Party's Issue to Closed This issue is solved by [Misc #15347]. In the C99 spec, The behavior of pow(3) in corner cases are clearly defined. Since Ruby 2.7, C99 is required to compile CRuby source code, and thus Ruby's pow method conforms to the C99 standard. ---------------------------------------- Bug #11582: On Solaris, Rational#** returns -Infinity for Rational(0) when passed a negative Float https://bugs.ruby-lang.org/issues/11582#change-103079 * Author: Eregon (Benoit Daloze) * Status: Closed * Priority: Normal * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN ---------------------------------------- For instance, > Rational(0, 1) ** -1.0 => +Infinity on most platforms, -Infinity on Solaris by default. The Rational is implicitly converted to the Float value 0.0, and the libm function pow(0.0, -1.0) is called. Should this kind of behavior be made consistent by Ruby or should we accept this as dependent on the libm/libc used? They are likely other edges cases for pow() which might differ, and I think in general Ruby should try to unify these cases so the behavior is consistent across platforms at least for arithmetic.
