Description of the illustration ''sin.gif''

Purpose

SIN returns the sine of n (an angle expressed in radians).

This function takes as an argument any numeric data type or any nonnumeric data type that can be implicitly converted to a numeric data type. If the argument is BINARY_FLOAT, then the function returns BINARY_DOUBLE. Otherwise the function returns the same numeric data type as the argument.
