finfo

finfo(type: dtype | array, /) → finfo_object

Machine limits for floating-point data types.

Parameters:

type (Union[dtype, array]) –

the kind of floating-point data-type about which to get information. If complex, the information is about its component data type.

Note

Complex floating-point data types are specified to always use the same precision for both its real and imaginary components, so the information should be true for either component.

Returns:

out (finfo object) – an object having the following attributes:

• bits: int

  number of bits occupied by the real-valued floating-point data type.

• eps: float

  difference between 1.0 and the next smallest representable real-valued floating-point number larger than 1.0 according to the IEEE-754 standard.

• max: float

  largest representable real-valued number.

• min: float

  smallest representable real-valued number.

• smallest_normal: float

  smallest positive real-valued floating-point number with full precision.

• dtype: dtype

  real-valued floating-point data type.

  New in version 2022.12.

Notes

Changed in version 2022.12: Added complex data type support.
