In HughParsonage/sillybiggies: What the Package Does (One Line, Title Case)

sillybiggies

The goal of sillybiggies is to perform arithmetic very large integers without a loss of precision. It achieves this in a silly way: each digit is allocated to an integer vector and arithmetic is performed in the schoolboy way. (i.e. carrying the ten for addition)

Installation

You can install sillybiggies using devtools:

# install.packages("devtools")
devtools::install_github("hughparsonage/sillybiggies")

Example

This is a basic example:

library(sillybiggies)
add_int(555, 555)

Because of the R parser, you can just enter large numbers directly as they will be intercepted with a loss of precision immediately. You can either enter them as strings

add_int("235972350923095820938523095", "2039529035709235905231")

or by separating any digits with pipes

add_int(235972350923|095820938523095, 20395290|35709235|905231)
