There are several (free) Pascal libraries for BigInteger (and sometimes Big Decimals like 1.23) functionality. Note: the C-based GMP library can also be used in Free Pascal, it's not listed here.
TForge
- By: Sergey Kasandrov
- Homepage: https://github.com/Alexey-T/TForge-Pascal
Modern cryptographic library for Delphi and Lazarus/FPC implemented as a set of runtime packages. Project development was stopped, the last found snapshot v0.76 was put to GitHub.
Big Decimal Math
- By: Benito van der Zander
- Homepage: https://benibela.de/sources_en.html#bigdecimalmath
This unit provides a BigDecimal-Type which stores arbitrary precision (BCD) decimal numbers and can be used like any native numeric type.
FNX
- By: Marcel Martin
- Homepage: https://www.ellipsa.eu/public/fnx/fnx.html
Library of multi-precision numbers (currently, only big integers) written for Free Pascal and Linux. The assembler code that can be enabled with a compiler directive, is for x86-64 processors only.
MPArith
- By: Wolfgang Ehrhardt
- Homepage: https://github.com/Alexey-T/Wolfgang_Ehrhardt_codes/tree/master/Misc/MPArith
Project development was stopped in about 2018. The last found snapshot was put to GitHub.
BigInt
- By: Franco Milani
- Homepage: http://spazioinwind.libero.it/frm/software
Though this is a Pascal source >90% are coded as x86-32 Win32 assembler routines.
HugeInt
- By: David J Butler
- Homepage: https://github.com/fundamentalslib/fundamentals5
Part of a much larger library but the unit can be used self-contained.
LongMathForPascal
- By: Zsolt Szakaly
- Homepage: https://github.com/zsoltszakaly/longmathforpascal
A quite recent contribution (2021) - unfortunately it does not support any efficient algorithms and becomes slow very fast.
GInt
- By: Walied Othman
- Homepage: https://github.com/SnakeDoctor/FGInt
Again part of a larger library but can be used self-contained.
BigIntegers for Delphi
- By: Rudy Velthuis
- Homepage: https://github.com/rvelthuis/DelphiBigNumbers
Code can be adapted for Free Pascal with a little effort.
