Модуль для работы с ОЧЕНЬ БОЛЬШИМИ целыми числами. В качестве примера приведены программы для решения уравнения Пэлла abs(x*x - n*y*y)=1 и вычисления чисел Бернулли.
Sometimes it is necessary to do arithmetic with integer numbers that are much bigger than the numbers a ordinary "integer" or "longint" variable can hold, and one has to keep even the last decimal, so using reals is not a solution. The "TInfint" object soves this problem by defining an integer with a size that is only limited by the available heap space.

Модуль математических функций для TP4: Тригонометрия, гиперболические и логарифмические функции.
Mathematical Turbo Pascal unit source (all versions from Turbo Pascal 4). Trigonometric, hyperbolic and logarithm functions.

This unit contains vector and matrix procedures and functions for TURBO-PASCAL, partly written as inline assembler code for a 387 coprocessor. They are about two to three times faster than the equivalent "pure PASCAL" code.
