Python is dynamically typed language. What is such processing that would work with iNaN, but doesn't work with float('nan')?
One simplistic example would be print(int(float('nan'))) (gives a ValueError) while print(int(iNaN)) should give 'nan' or maybe 'inan'.
Why do you convert to int when you need a string representation? Just print(float('nan')). I converted to int because I needed a whole number, this was intended to represent some more complex process where a value is converted to a whole number down in the depths of the processing.
Your requirement to have a whole number cannot meaningfully be satisfied if your input is nan so an exception is the most useful result. -- Oscar
