Return type: Opaque Returns: The cosine of a floating point number. |
define external float function
cos value float x
Use cos to calculate the cosine 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 "Cosine of x, where x = (pi * 2), is "
|| "d" % cos (pi * 2)
|| "%n"
; Output: "Cosine of x, where x = (pi * 2), is 1"
