acos()

The Mathematical Function acos() returns the cosine angle in radian measure for the value of the parameter "number".

Syntax of the Mathematical Function acos()

    acos(number)
    

The parameter "number" of the Mathematical Function acos()

number
The parameter "number" is a placeholder for a column name, variable or a constant, which has to be available as float, real, double precision datatypes. Additionally, the parameter "number" recognises any other datatype that can be converted with implicit conversion into one of the required datatypes.

Example for the Mathematical Function acos()

    select acos(0.5)

    go

    -----

    1.047198
    

Returns the cosine value in radian measure of the value 0.5.

    select degrees(acos(0.5))

    go

    -----

    60.000000
