# SIN

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.

See Also: Table 2-10, "Implicit Type Conversion Matrix" for more information on implicit conversion

Examples

The following example returns the sine of 30 degrees:

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

    Sine of 30 degrees
