Sized Integers

[srogers]

I am trying to discover how to declare an integer in MicroPython as a particular size (or signed type).

I'd like the capability to do these types (expressed in 'C' or "C++' notation:

Code: Select all

int_8
uint_8
int_16
uint_16
int_32
uint_32

How is this done in MicroPython 1.18?

Micropython has 2 representations of an integer. One is SMALLINT which doesn't require heap allocation and is a 31-bit signed number. The second is an infinite precision integer which can have as many digits as it needs.

For creating sized data structures, for storing to disk, sending over the serial/network, etc, you can use the uctypes or struct
