这些天，浮点数学一般是硬件的设计处理的完整宽度浮点类型。

These days, floating-point math is typically done in hardware that's designed to handle the full width of the floating-point types.

是一个十进制数，所有的结果都充分考虑整数乘法，浮点数学吗？

Is Multiplying a decimal number where all results are full integers, considered Floating Point Math?

由有限精度浮点数字引起的很小的舍入错误就会严重歪曲数学精度计算。

Mathematically precise calculations can be thrown severely askew by small round-off errors caused by finite-precision floating-point Numbers.

0 >> David: Yeah, so I very deliberately changed this 9 to a 9.0 so that my math would actually be floating point math involving real numbers and not just integers.

>，大卫：是的，我故意地把9改成9,那样我的数学实际上就是浮点数的了,包括实数，不只是整数。
