function
Library: Trigonometry (OMTRIG legacy)
Include: omtrig.xin |
Returns: the tangent of a floating point number |
define external float function tan value float x
Use tan to calculate the tangent of an angle in radians. The angle must be a floating point number. This trigonometric function works the same way as its equivalent in the C math library.
Out-of-range values return "not a number" (NaN).
Example:
include "omtrig.xin" process output "The tangent of pi/3 is " || "d" % (tan (pi / 3)) || " %n" ; Output: "The tangent of (pi/3) is 1.732050807568877"
