| arctan | arctangent function (radians) |
| Syntax | arctan (r : real) : real
|
| Description | The arctan function is used to find the arc tangent of a value. The result is given in radians. For example, arctan (1) is p / 4.
|
| Example | This program prints out the arctangent of 0 through 3 in radians.
for i : 0 .. 12
const arg := i / 4
put "Arc tangent of ", arg, " is ",
arctan (arg), " radians"
end for
