Previous behaviour was inconsistant and was not tested for. This commit ensures that z^inf and inf^z return reasonable and consistant values. See infusion#24 for the dicussion on the behaviour which can be summaried as: z ^ Infinity === NaN Infinity ^ z === Infinity if Im(z) === 0 and Re(z) > 0 Infinity ^ z === 0 if Re(z) < 0 Infinity ^ 0 === 1 Infinity ^ z === NaN otherwise

There was a problem hiding this comment.
Should the imaginary part of z be compared exactly to 0 here or should Complex['EPSILON'] be used?

@infusion could you take a look? |

@infusion I have solved the merge conflicts, would it be possible to review this? |
