About Calc Pro - Simple and Useful
Calc Pro can do complicated calculations easily. It is a very powerful math calculator but easy to use. Calc Pro also handles huge numbers without ellipsis. Most calculators will only handle calculations involving numbers with up to 13 digits, but this one allows for larger and more precise calculations, supporting up to 15 digits of precision to the right of the decimal, and big enough digits to the left. Calculation history won't be lost when the app is closed. You can reuse calculation equations and answers by tapping. Calc Pro also supports mathematical functions like square root, logarithm, combinations, and permutation. You can easily access these functions by swiping. Features: - Arithmetic - Calculation with parentheses - Dark Mode - Huge Number Handling - Copy calc answer with a long press - Calculation history - Scientific calculation - Swipe to change the keyboard easily
