The SIN Function

The SIN function returns a numeric value that approximates the sine of an angle or arc, expressed in radians, that is specified by argument-1. The type of this function is numeric.

General Format



  1. Argument-1 must be class numeric.
    Note: Conversion factors from degrees and Gon (grad) to radians are specified in the section Trigonometric Functions.

Returned Values

  1. The returned value is the approximation of the sine of argument-1 and is greater than or equal to -1 and less than or equal to +1.
  2. Floating-point format is used for numeric non-integer results.
