$atan returns the arctangent of N.
Synopsis[edit]
$atan(N)[.deg]
Parameters[edit]
NThe tangent in radians for which you want the arc tangent.
Properties[edit]
.degReturns the angle as degrees, default is radians.
Example[edit]
//echo -a In right triangle where opposite side is 3 and adjacent is 4, angle is $atan( $calc(3/4) ).deg degrees ; Returns: In right triangle where opposite side is 3 and adjacent is 4, angle is 36.869898 degrees
//var %i 60 | echo -a %i degrees / tangent $tan(%i).deg / atan $atan( $tan(%i).deg ).deg ; returns 60.000003 instead of 60 because the $tan fraction is limited to 6 places //var %i 45 | echo -a %i degrees / tangent $tan(%i).deg / atan $atan( $tan(%i).deg ).deg //var %i 240 | echo -a %i degrees / tangent $tan(%i).deg / atan $atan( $tan(%i).deg ).deg ; returns angle in the range of -90 - +90 degrees (-pi/2 - +pi/2 radians) //var %i 90 | echo -a %i degrees / tangent $tan(%i).deg / atan $atan( $tan(%i).deg ).deg ; for 90 degrees, returns a VERY BIG NUMBER instead of infinity
Compatibility[edit]
Added: mIRC v5.3
Added on: 13 Dec 1997
Note: Unless otherwise stated, this was the date of original functionality.
Further enhancements may have been made in later versions.
