Syntax	tand ( r : real ) : real
Description	The tand function is used to find the tangent of an angle given in degrees. For example, tand (45) is 1.
Example	This program prints out the tangent of 0, 30, 60, 90, up to 360 degrees. for i : 0 .. 12 const angle := i * 30 put "Tan of ", angle, " is ", tand ( angle ) end for
Execute
Details	An argument to tan of 90, 270, etc. may result in an overflow (and halt of the program) as the result is technically ¥. (It may not cause an overflow due to rounding, in which case the result will simply be a very large number.)
See also	the sind and cosd functions for calculating sine and cosine. the tan function which finds the tangent of an angle given in radians. (2p radians are the same as 360 degrees.) See also predefined unit Math.
