Difference between Python float and numpy float32

Question

What is the difference between the built in float and numpy.float32?

For example, here is a code:

a = 58682.7578125
print type(a)
print a
print type(numpy.float32(a))
print numpy.float32(a)
 

The output will be :

<type 'float'>
58682.7578125
<type 'numpy.float32'>
58682.8

What is the built in float format?

Answer 1

Python's standard float type is a C double.

NumPy's standard numpy.float is the same, and is also the same as numpy.float64
