floating-point overflow 中文意思是什麼
floating-point overflow
解釋
浮點溢出-
Floating - point arithmetic overflow or division by zero never throws an exception, because floating - point types are based on ieee 754 and so have provisions for representing infinity and nan not a number
浮點算術溢出或被零除從不引發異常,因為浮點類型基於ieee 754 ,因此可以表示無窮和nan (不是數字) 。 -
If overflow occurs converting a floating - point type to an integer the result
如果在將浮點類型轉換為整數類型時發生溢出,則返回的 -
While floating - point data is stored in the fprs in double - precision format, a set of single - precision arithmetic instructions perform the arithmetic operation and round the final result to single - precision while detecting exceptions such as exponent overflow, underflow, and inexact that should occur with a single - precision operation
雖然浮點數以雙精度格式存儲于fpr中,但是,有一組單精度運算指令,可以執行運算操作並將最終結果舍入為單精度,同時檢測進行單精度操作時可能會發生的異常(比如指數溢出、下溢和失去精度) 。 -
