Mathematical operators
Mathematical operators can be used with numerical values and variables. They can also be used inside of command parameters.
The following mathematical operations are implemented in Descript:
| Operator | Name | Syntax example | Description |
|---|---|---|---|
| + | Summation | 1+2 | Adds numbers |
| - | Subtraction | 3-2 | Subtracts numbers |
| * | Multiplication | 4*2 | Multiplies numbers |
| / | Division | 1/2 | Divides numbers |
| % | Modulo | 11%3 | Gives back remainder |
| ^ | Exponent | 2^3 | Gives back exponent |
| sin | Sine | sin(30) | Gives back sine of degree input |
| cos | Cosine | cos(30) | Gives back cosine of degree input |
| tan | Tangent | tan(30) | Gives back tangent of degree input |
| log | Logarithm (base 10) | log(100) | Gives back base 10 logarithm |
| round | Rounding | round(1.23) | Rounds a number |
| floor | Rounding down | floor(1.23) | Rounds down |
| ceil | Rounding up | ceil(1.23) | Rounds up |
| nint | Nearest integer | nint(1.23) | Gives back nearest integer |
| sqrt | Square root | sqrt(2) | Gives back square root |
| min | Minimum | min(1;2) | Minimum of 2 numbers |
| max | Maximum | max(1;2) | Maximum of 2 numbers |
| abs | Absolute value | abs(-123) | Gives back absolute value |
