SIN

The SIN function returns the sine of the argument, where the argument is an angle expressed in radians. The SIN and ASIN functions are inverse operations.

SIN(expression)

expression: An expression that returns a value of any built-in numeric data type (except for DECFLOAT), character-string, or graphic-string data type. A string argument is converted to double-precision floating point before evaluating the function. For more information about converting strings to double-precision floating point, see DOUBLE_PRECISION or DOUBLE.

The data type of the result is double-precision floating point. If the argument can be null, the result can be null; if the argument is null, the result is the null value.

Example

Assume the host variable SINE is a decimal (2,1) host variable with a value of 1.5.
```
  SELECT SIN(:SINE)
    FROM SYSIBM.SYSDUMMY1
```
Returns the approximate value 0.99.
