NumPy's finfo(~) method returns information about a particular NumPy float data type. Information includes the number of bits occupied by that data type, and the maximum and minimum limits of supported values.

Parameters

1. type | dtype

The float data type or an instance of one to retrieve information about.

Return value

A <class 'numpy.finfo'> object with key information such as:

  • Minimum supported value of the provided float data type

  • Maximum supported value of the provided float data type

  • Precision of the provided float data type

Examples

Basic usage

To retrieve information on the float32 data type:

np.finfo(np.float32)
finfo(resolution=1e-06, min=-3.4028235e+38, max=3.4028235e+38, dtype=float32)

min

To retrieve the minimum allowed value for float32:

np.finfo(np.float32).min
-3.4028235e+38

max

To retrieve the maximum allowed value for float32:

np.finfo(np.float32).max
3.4028235e+38

precision

To retrieve the precision for float32:

np.finfo(np.float32).precision
6

We can see that float32 floats are precise to approximately 6 decimal places.
