NumPy array numerical data types

Python offers three types of numerical data types: integer type, float type, and complex type. In practice, we need more data types for scientific computing operations with precision, range, and size. NumPy offers a bulk of data types with mathematical types and numbers. Let's see the following table of NumPy numerical types:

Data Type

Details

bool

This is a Boolean type that stores a bit and takes True or False values.

inti

Platform integers can be either int32 or int64.

int8

Byte store values range from -128 to 127.

int16

This stores integers ranging from -32768 to 32767.

int32

This stores integers ranging from -2 ** 31 to 2 ** 31 -1.

int64

This stores integers ranging from -2 ** 63 to 2 ** 63 -1.

uint8

This stores unsigned integers ranging from 0 to 255.

uint16

This stores unsigned integers ranging from 0 to 65535.

uint32

This stores unsigned integers ranging from 0 to 2 ** 32 –...
