Proposal: mpmath.isfinite() #244

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Both numpy and Python (beginning with version 3.2) have a function called 
`isfinite()`, which returns True if the argument is neither an infinity nor a 
NaN, and False otherwise.

While porting some standard Python code to use mpmath, I noticed that there is 
no function `mpmath.isfinite()`.  I think it would be a great and useful thing 
to add, and would supplement nicely `mpmath.isnan()` and `mpmath.isinf()`, 
which already parallel the versions in python's `math` module.
