This PR

  • adds complex number support to asarray. Importantly, if one or more values are complex numbers, the output data type must be the default complex floating-point data type.

I fail to see why complex should appear before (or after) float with the "precedence" clause, I must be missing something...

@leofang Because if at least one value is complex, then the returned array must have a complex data type. Hence, if provided a mixture of complex and float, complex takes precedence. This is similar to type promotion semantics.
