Calculates the cosine of a number.
|number||a number, or an expression that evaluates to a number|
Number, with the same number of decimal places as number.
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
without any decimal points, you receive the result
However, if you enter
you receive the result
Evaluates to 1.
let var1 = 3.14
let var2 = $cos(0.50*var1)
Var2 evaluates to 0.00.
