A function in the [expr] command that computes the '''tangent''' of an angle. The angle is expressed in radians.

2007-11-01 Harm Olthof: I was just wondering how to get [tan] return +/-[Inf] (and what choice it would make for the sign).
 59 % expr tan(acos(0))
  16331778728383844.0
 60 % expr tan(acos(0.0))
  16331778728383844.0
 61 % set pi 3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342117068
 62 % expr tan(double($pi/2.0))
  16331778728383844.0

[EKB] What version of Tcl are you using? (By the way, this should probably go to [comp.lang.tcl] instead of here.)

[LV] Actually, this is a fine place to ask questions like this. On the other hand, asking on comp.lang.tcl is a fine place to get answers as well.
