Goes someway towards addressing #804.
Tests pass with current behaviour of complex.js and will need updating when full support of infinite numbers is added there.
New behaviour of pow function:
(-2)^Infinity = ComplexNAN
(-1)^Infinity = ComplexNAN
(-0.5)^Infinity = 0
(real)(-2)^(-Infinity) = 0
(real)(-0.5)^(-Infinty) = ComplexNaN
If
config.predictible = true
results are the same butComplexNaN
becomesNaN
