Calculates the tangent of a number.

Syntax

$tan(number)

Parameters

Return Value

Number, with 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

$tan(3)

without any decimal points, you receive the result

-0

However, if you enter

$tan(3.0000)

you receive the result

-0.1425

Comments

The value returned by this function has the same number of decimal places as number.

let var1 = $tan(0)
let var1 = 3.14
let var2 = $tan(0.50*var1)
