ATan( <expression> )
</pre>

=== Description ===

Calculates the arctangent of a number.

=== Parameters ===

==== expression ====

Any valid numeric expression.

=== Return Value ===

Returns the trigonometric arctangent of expression. Result is in radians..

=== Remarks ===

The result of 4 * ATan(1) is PI.

=== Example ===

<syntaxhighlight lang="sputnik">
$x = ATan(0.5);
$pi = 4 * ATan(1);
$radToDeg = 180 / @PI;
$y = ATan(1) * $radToDeg;
println( "Value is: $y " ); //arctangent of 1 returns 45°
