Precise Calculator

Precise Calculator by Petr Laštovička is a free, open-source scientific calculator for Windows that calculates with arbitrary precision, up to millions of significant digits. It is useful for mathematics, science and engineering tasks where ordinary calculators lose accuracy, and it works with complex numbers, fractions, vectors and matrices as well as ordinary numbers.

Calculates with extreme precision where ordinary calculators round off.

More than 150 mathematical and statistical functions are built in, and calculations can be programmed with conditions, jumps and output commands, macros and any number of variables. Physical constants and unit conversions are available, the command history can be reused and results logged to a file. The program is portable and comes in 32-bit, 64-bit and console builds.

Features:

• Arbitrary precision calculation
• Complex numbers, fractions, vectors and matrices
• Over 150 math and statistics functions
• Programmable with variables and macros
• Physical constants and units
• Portable 32-bit, 64-bit and console builds
