atan()
The
Mathematical Function
atan()
returns the arc tangent angle in radian measure for the value of the parameter "number"
.
Syntax of the Mathematical Function atan()
The parameter "number" of the Mathematical Function atan()
number
The parameter "number" is a placeholder for
column names,
variables
or
constants,
which have to be available as
float,
real,
double precision
datatypes. Additionally, the parameter "number" recognises any other datatype which can be converted with
implicit conversion
into any of the required datatypes.

Returns the arc tangent in radian measure of the value 1.
select degrees(atan(1))
go
-----
45.000000
