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(shù)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(zhí)行運算操作并將最終結(jié)果舍入為單精度,同時檢測進(jìn)行單精度操作時可能會發(fā)生的異常(比如指數(shù)溢出、下溢和失去精度) 。
