bigintcalc

Enables expandable arithmetic operations on integers beyond standard TeX number size limitations.

Overview

Provides essential functionality for handling and manipulating extremely large integer values that would normally exceed TeX's built-in numerical constraints. This specialized package is particularly valuable in:

  • Complex mathematical computations requiring precise handling of large numbers
  • Document automation where large numerical calculations are needed
  • Technical documentation involving extensive numerical processing
  • Scientific computing applications within TeX documents

The package performs calculations entirely through TeX's expansion mechanism, making it suitable for use in expandable contexts where traditional arithmetic operations would fail due to size limitations.

Getting Started

To use bigintcalc, include it in your document preamble:

\documentclass{article}
\usepackage{bigintcalc}

This package provides expandable arithmetic operations for working with integers that exceed TeX's built-in number limits.

Examples

Performing arithmetic operations with very large integers beyond TeX's number limits.

\noindent
Standard TeX can only handle integers up to $2^{31}-1 = 2147483647$.

Using \texttt{bigintcalc} for large integer calculations:

Factorial of 30: $\bigintcalcFac{30} = 265252859812191058636308480000000$

\bigskip
\noindent
Multiplying two large numbers: $\bigintcalcMul{9876543210}{9876543210} = 97546105778997104100$

\bigskip
\noindent
Adding large numbers: $\bigintcalcAdd{12345678901234567890}{98765432109876543210} = 111111111011111111100$
