How to check if a number is a np.float64 or np.float32 or np.float16?
numpy, python
Solution
You can use `np.floating`:
In [11]: isinstance(np.float16(1), np.floating)
Out[11]: True
In [12]: isinstance(np.float32(1), np.floating)
Out[12]: True
In [13]: isinstance(np.float64(1), np.floating)
Out[13]: True
Note: non-numpy types return False:
In [14]: isinstance(1, np.floating)
Out[14]: False
In [15]: isinstance(1.0, np.floating)
Out[15]: False
to include more types, e.g. python floats, you can use a tuple in isinstance:
In [16]: isinstance(1.0, (np.floating, float))
Out[16]: True
Problem
Other than using a set of or statements `isinstance( x, np.float64 )` or `isinstance( x, np.float32 )` or `isinstance( np.float16 )` Is there a cleaner way to check of a variable is a floating type?
