Syntax

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

SELECT SIN(30 * 3.14159265359/180)
 "Sine of 30 degrees" FROM DUAL;
