Comments

The value returned by this function has the same number of decimal places as number. Ensure that you specify enough decimal places in your equation to ensure a sufficiently granular result. Unusual results such as
-0 are an indication that the number of decimal places needs to be increased. For example, if you enter

$sin(4)

without any decimal points, you receive the result

-1

However, if you enter

$sin(4.0000)

you receive the result

-0.7568

Example

let var1 = $sin(0)

Evaluates to 0.
