Open Source Bignum Calculator with up to 306 Decimal Digits

SUMMARY: TTCalc performs calculations with a high degree of precision, and also supports user-defined functions and variables.

If you need a Windows calculator with a high degree of decimal precision, consider the open-source TTCalc. This bignum calculator supports precision from 26 decimal digits all the way to 306. Numbers up to having an exponent of 99 can be displayed normally before being shown in scientific notation.

TTCalc supports basic mathematical functions as well as trigonometric (sine, cosine, tangent, plus hyperbolic and inverse hyperbolic functions). Several pre-made functions are included such as rounding, floor, ceiling, average, minimum, and maximum. The software also supports user-definable variables and functions.

Displaying very large numbers in TTCalc

Besides adjusting the precision and displayable digits without using scientific notation, other customization options include the input and output bases (such as binary and hexadecimal), number grouping which may make larger numbers easier to see, and characters to use for the decimal point and for separating function parameters. Seven interface languages are supported including Chinese, Spanish, and Russian.
