posit-playground 0.1.3

Posit arithmetic library with no frills

posit-playground

Goals:

• output nice bit representations
• build posit from_double and from_bits
• implement basic math operations
  • add/sub
  • mul
  • div

Install

• stable

pip install posit-playground

Usage

from posit_playground import from_bits, from_double

p1 = from_bits(
    bits=0b000110111011101,
    size=16,
    es=3,
)

p2 = from_double(
    x=2.312,
    size=6,
    es=1,
)

p1 * p1 # implements posit multiplication
