The Calc 3.02

The Calc is a multifunctional calculator, a converter of physical units, a calculator of dates and a converter of calendars, a universal solver of algebraic equations.

The Calc calculates arithmetic and parenthesis operations, trigonometric functions, natural, binary, decimal and arbitrary logarithms, power and exponential functions, modulus, factorial. Both the expression and the result can be represented in any calculus system from binary to hexadecimal, and, unlike most other calculators, not only integers, but also fractional numbers can be written in non-decimal calculus systems. Trigonometric expressions can be calculated in degrees or radians, and both numbers in degrees and numbers in radians can be arbitrarily mixed in one expression. It is also possible to work not only with decimals, but also with natural fractions.

It is possible to work with both the mouse and the keyboard, and when working with the keyboard, it is permissible to use only the Russian layout. There is an unlimited number of conveniently managed memory cells, an unlimited number of user-defined functions and constants connected on the fly, accuracy from 0 to 16 decimal places.

The built-in unit conversion module contains more than 650 units of measurement divided into 21 categories, which puts it on the level of the most advanced programs of this kind. The date module can not only add and subtract dates and periods and calculate the day of the week of any date, but also can convert the date between the main current calendars Gregorian, Julian, Muslim (lunar Hijri), Jewish.

The equation solving module allows solving any algebraic equations of the form f(x)=0, for example 2*x^2-20x+10=0 or SQRT(5*x^12)-(cos(x^3))^3+ln(x)=0.

In the accounting mode, the calculator performs operations with interest, adds / subtracts / allocates 10% and 18% VAT, calculates the main Russian taxes. Can copy the result in text. Calculates 18 financial functions(annuity, depreciation, etc.)

In the chemical mode, the periodic table is presented (it can be depicted in several different forms) and a lot of data for each element. It is possible to calculate the molecular weight of a substance, the percentage composition of elements in a substance, the equalization of complex chemical reactions, and unlike many other programs of this kind, where complex reactions can be equalized for tens of minutes, TheCalc usually equalizes reactions in fractions of a second.
