Scientific calculator Kal

一个包含数学函数的完整科学计算器

Scientific calculator Kal is a very complete scientific calculator, containing most mathematical functions and with the ability to perform graphics functions.

It includes a library with one hundred (100) mathematics and physics formulas ready to use, which generate a result after entering the value of its variables. It also allows you to easily extend the library with your own formulas or functions.

It is very easy to use like a real calculator, includes a display for writing operations without a character limit, and allows you to use parentheses and respects the hierarchy of expressions. The results are displayed on the second line of the display with the ability to update or correct any character when there is an error in the expression.

Scientific calculator Features:

• Allows make function graphs.
