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 虽然浮点数以双精度格式存储于fpr中,但是,有一组单精度运算指令,可以执行运算操作并将最终结果舍入为单精度,同时检测进行单精度操作时可能会发生的异常(比如指数溢出、下溢和失去精度) 。
