SIN¶

引数のサインを計算します。引数はラジアンで表現する必要があります。

構文¶

SIN( <input_expr> )

引数¶

input_expr: The value or expression to operate on. The value must be in radians, not degrees. The data type must be FLOAT or DECFLOAT.

Returns¶

If the input expression is of type DECFLOAT, the returned type is DECFLOAT. Otherwise, the returned type is FLOAT.

例¶

SELECT SIN(0), SIN(PI()/3), SIN(RADIANS(90));
--------+--------------+------------------+
 SIN(0) | SIN(PI()/3)  | SIN(RADIANS(90)) |
--------+--------------+------------------+
 0      | 0.8660254038 | 1                |
