Paste To external

One click Transfer To your
word processor, accounting and other external applications.

Expressions can be simple or quite complex mathematical formulas
Either way the Expression Evaluator is easier and faster to work with than pocket calculators.

Multi precision

RICalc has an internal multi-precision engine capable of performing calculations to an arbitrary precision of millions of digits of accuracy.

Multi precision is used in RICalc for calculation of mathematical constants, such as pi, e, euler to high precision, and to improve accuracy in functions such as factorials, gamma, beta, root finder, integrals, trigonometry, polynomial, complex and other functions.

Most multi-precision implementations are already available in EE and in Functions.

Calculate algebraic expressions to high-precision.

Click for Functions multi-precision calculator screen shot

Arbitrary precision to millions of digits



400+ predefined functions for:

Math, Trigonometry, Statistic, Financial, Conversion, Logical, Text, Date, Information, Geometry, and more...

Create and store your own functions.

Functions prefixed with MP, perform arithmetic computation in arbitrary precision.

Non MP functions with precision parameter in the argument list, compute in either IEEE or in MP.

Click for Functions calculator screen shot


Select select MP format in the Expression Evaluator and most expressions are performed in high-precision.


How can you use the Scientific calculator and Expression Evaluator?
For rapid calculations, use the Expression Evaluator and one-click paste to external applications.
For general calculations, use the General - Scientific calculator.
For multi precision and to solve hundreds of functions, use Functions.
For Time, use the Date calculator and the others tools for quick and easy calculations.

Clear and easy calculators for what matters Save time, concentrate on the important things Save time

All-in-one true calculator, not several, just one.
