decimal arithmetic

基本解釋

The POWER6 has hardware support for decimal arithmetic.
POWER6 為十進(jìn)制計(jì)算提供硬件支持。
There are some cases where arbitrary-precision decimal arithmetic is still not sufficient to maintain exact results.
另外還有一些情形，任意精度的小數(shù)運(yùn)算仍不能表示精確結(jié)果。
That's more than adequate for most tasks, but you do need to keep in mind that it's not decimal arithmetic, and that every float operation can suffer a new rounding error.
但是，我們還是要牢記我們做的并不是十進(jìn)制運(yùn)算，任何一個(gè)浮點(diǎn)預(yù)算都有可能產(chǎn)生一個(gè)新的錯(cuò)誤。

Calculations by scientists, who are forever totting up times but are often bad at mental arithmetic, will also be much easier if they can just move decimal points instead of multiplying and dividing.
