A constant expression must yield a value of the target type, or of a type that can be implicitly converted to the target type. 常數表達式必須產(chǎn)生具有目標類(lèi)型或者可隱式轉換為目標類(lèi)型的類(lèi)型的值。
Previous studies have shown that the MDCT analysis results of pure sinusoids can be approximated by using the product of a constant, a cosine function, and a decay function. 由先前的研究，一個(gè)正弦波訊號的修正式離散馀弦轉換分析結果可以由一個(gè)常數，一個(gè)馀弦函數與一個(gè)衰減函數的乘積所逼近。
