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.
在大部分的编程语言中，包含了小数点的数字称之为浮点数，可以用它来表示数学中的实数。
In most programming languages, Numbers that include a decimal fraction are called floating-point Numbers, which are used to approximate real Numbers in mathematics.
在整数和浮点数上，都支持使用标准的数学操作符（+、-、/ 和 *），可以在算式中混合使用浮点数和整数。
The standard mathematical operators, +, -, /, * are supported on both integer and floating point values, and you can mix and match floating-point and integers in calculations.
记住，整形数运算要比浮点数运算快得多，因为处理器可以直接进行整型数运算，浮点数运算需要依赖于外部的浮点数处理器或者浮点数数学库。
Remember, integer arithmetic is much faster than floating-point arithmetic, as it can usually be done directly by the processor, rather than relying on external FPUs or floating point math libraries.
