exponent underflow 中文意思是什麼
exponent underflow
解釋
階碼下溢-
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） 。
