Check if python int is too large to convert to float

Question

Is there any way to check if a long integer is too large to convert to a float in python?

Answer 1

>>> import sys
>>> sys.float_info.max
1.7976931348623157e+308

Actually, if you try to convert an integer too big to a float, an exception will be raised.

>>> float(2 * 10**308)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
