ATan( <expression>, <expression2> )
Contents |
Description
Calculates the arctangent of a number.
Parameters
expression
Any valid numeric expression.
Return Value
Returns the trigonometric arctangent of expression.
Remarks
The result of 4 * ATan(1) is PI.
Example
$x = ATan(0.5); $pi = 4 * ATan(1); $radToDeg = 180 / @PI; $y = ATan(1) * $radToDeg; println( "Value is: $y " ); //arctangent of 1 returns 45°
