# How to use functions and constants in your calculations

You can use mathematical functions and constants (including dates and times) inside each calculation block.

## When to use

Use the calculator block when you want to perform calculations inside your form. If you want to perform calculations with advanced operations, that's possible with the built-in mathematical functions and constants (including dates and times) in the calculator block. For example:

• Get the highest value of two given answers and use that highest value in a calculation;
• Perform a mathematical formula to determime the circumference of a circle.

These are just some examples. Basically you can calculate anything you want with the calculator block. Please have a look at our calculator features overview to see everything you can do with the calculator block.

## How to use

You can use the advanced options inside each operation. From the menu to add an operation, you will see a menu item `Function` (if you have an empty form, you will see these menus directly). This includes all functions and constants, grouped by the type of function.

### Setup function/constant

You can use all kinds of mathematical functions to help you perform the right calculations. The available functions are divided into the following categories:

• `Limiting` - Contains functions to limit certain values, like `min`, `max` and `clamp`;
• `Floating point` - Contains functions to work with floating point values, like `round`, `floor` and `ceil`;
• `Exponentiation` - Contains functions to perfom exponentiation, like `powers`, `roots` and `exponents`;
• `Trigonometry` - Contains functions to perform trigonometrial calculations, like `sin`, `cos` and `tan`;
• `Factorial` - Contains functions to perform factorial calculations, like `n!` and `gamma`;
• `Miscellaneous` - Contains miscellaneous functions, like `absolute`, `modulus` and `percentage`;
• `Constants` - Contains constans, like `π ≈ 3.14159`, `e ≈ 2.71828` and `c = 299,792,458 m/s`, but also date and time constants, like `year`, `month`, `day (of month)` and `day (of week)`;

After selecting the right function/constant, it depends on the selected function/constant what properties are available to configure the operation.

Please have a look at our calculator features overview to see all functions and constants you can use in the calculator block.

The calculator block has lots of features, so we have several ways to learn all about it.
