$atan2 returns the arctangent of the 2 short sides of a right triangle.
Synopsis
$atan2(<O>,<A>)[.deg]
Parameters
OThe length of the Opposite side of the right triangle.
AThe length of the Adjacent side of the right triangle.
Properties
.degReturns the angle as degrees, default is radians.
Example
//echo -a In right triangle where adjacent side is 3 and opposite side is 4, angle is $atan2( 3 , 4 ).deg degrees ; Returns: In right triangle where adjacent side is 3 and opposite side is 4, angle is 36.869898 degrees
//var %opposite 3 | var %adjacent 4 | echo -a $atan2(%opposite,%adjacent) is the same as $atan( $calc( %opposite / %adjacent ) ) ; ATAN2 accepts the side lengths while ATAN accepts the tangent ratio of those sides
Compatibility
Added: mIRC v7.33
Added on: 27 May 2014
Note: Unless otherwise stated, this was the date of original functionality.
Further enhancements may have been made in later versions.
