カテゴリ:数値関数 (三角関数) COS¶ 引数の余弦を計算します。引数はラジアンで表現する必要があります。 構文¶ CopyExpandCOS( <input_expr> ) Show lessSee moreScroll to top 引数¶ input_exprThe value or expression to operate on. The value must be in radians, not degrees. The data type must be FLOAT. 戻り値¶ This function returns a value of type FLOAT. 例¶ CopyExpandSELECT COS(0), COS(PI()/3), COS(RADIANS(90)); Show lessSee moreScroll to top Expand+--------+-------------+------------------+ | COS(0) | COS(PI()/3) | COS(RADIANS(90)) | |--------+-------------+------------------| | 1 | 0.5 | 6.123233996e-17 | +--------+-------------+------------------+ Show lessSee moreScroll to top
