NumPy numerical types

Python has an integer type, a float type, and complex type; nonetheless, this is not sufficient for scientific calculations. In practice, we still demand more data types with varying precisions and, consequently, different storage sizes of the type. For this reason, NumPy has many more data types. The bulk of the NumPy mathematical types ends with a number. This number designates the count of bits related to the type. The following table (adapted from the NumPy user guide) presents an overview of NumPy numerical types:

Type

Description

bool

Boolean (True or False) stored as a bit

inti

Platform integer (normally either int32 or int6 4)

int8

Byte (-128 to 127)

int16

Integer (-32768 to 32767)

int32

Integer ...
