| 项目描述: |
My PPC device runs for a fairly long time on a watch battery and a pair of AAAs. I wasn't too surprised, then, when I found part of the reason for this long battery life is that my palmtop has a limited register set and it doesn't have chip support for much floating-point math. Try as I might, I simply couldn't rearrange program logic in a way that would get rid of unresolved externals that had to do with floating point number comparisons. I finally wrote workarounds that transform floating point numbers to integers and then operate them.
我的PPC设备使用一个手表电池和一对AAA电池，用了很长时间。我发现这是因为我的掌上电脑使用了一套有限的寄存器，没有支持浮点计算的芯片。我试图解决这个问题，但我只是不能去掉和浮点数比较有关的计算操作。我最后将浮点数转换为整数，再操作它们。
