Calculates the tangent of a number.
$tan(number)
number | a number or an expression that evaluates to a number |
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
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)
