floating-point exponent 中文意思是什麼
floating-point exponent
解釋
浮點階-
In a floating ? point representation system, to make an adjustment to the fixed ? point part and the corresponding adjustment to the exponent in a floating ? point representation to ensure that the fixed ? point part lies within some prescribed range, the real number represented remaining unchanged
在浮點表示方法中,調整浮點表示中的定點部分和相應的指數,以保證定點部分處于預先規定的值域內,並使所代表的實數值保持不變。 -
The internal representation of a floating - point number, including the format and precision of the significand and the format and range of the exponent, is implementation defined
一個浮點數目的內部表示法,包含格式和有效的精確度及格式和指數的范圍,是實作自訂的 -
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) 。
