| 1. | The default rounding mode of the fpu is " round toward nearest . " using
Fpu的默认舍入模式为“舍入为最接近的整数” 。使用 |
| 2. | The rounding mode will be one of four as documented in intel reference manuals
舍入模式应是记录在intel参考手册中的四种模式之一： |
| 3. | Results in generation of the fistp instruction , which uses whatever ambient rounding mode is to do the conversion
导致生成fistp指令，该指令可使用任意环境舍入模式执行该转换。 |
| 4. | You should thoroughly test the portions of your code that are sensitive to rounding modes before relying upon code built with
生成的代码前，要彻底测试对舍入模式敏感的代码部分。 |
| 5. | And the compiler performs a floating - point calculation , the rounding mode you specified will not be in effect unless
更改舍入模式，并且编译器执行浮点计算，则指定的舍入模式将无效，除非打开 |
| 6. | Function ensures the rounding mode of the floating - point unit is toward zero truncate , by setting bits 10 and 11 of the control word
函数还通过设置控制字的第10位和第11位来确保浮点单元( fpu )的舍入模式为向零方向（截断） 。 |
| 7. | The floating - point status and control register fpscr captures status and exceptions resulting from floating - point operations , and the fpscr also provides control bits for enabling specific exception types , as well as for selecting one of the four rounding modes
浮点状态和控制寄存器（ fpscr ）捕获浮点操作的状态和异常结果， fpscr还具有控制位，以支持特定的异常类型和对四种舍入模式之一的选择。 |
