The layout of IEEE floating point values is shown in Figure 1.
ieee浮点值的格式如图1所示。
There we have merely 8 bytes for the two floating point values for the X and Y dimension.
对于X和Y维，我们只有用于两个浮点值的8个字节。
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.
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。
There are some libraries that can handle floating point values of arbitrary size.
有一些库，可以处理任意大小的浮点值。
This technique can especially help in finding problems with floating-point values, conversion ratios, and lengths associated with data types.
这项技术特别有助于发现使用浮点值、转换率，以及与数据类型相关长度的问题。
Editing floating-point values can result in minor inaccuracies because of decimal-to-binary conversion of fractional components.
编辑浮点值时，由于要将小数部分从十进制转换为二进制，因此所得的结果可能存在微小误差。
For functions not fully prototyped, the caller will pass integer values as integers and floating-point values as double precision.
对于没有完整原型的函式，呼叫端将会传递整数值做为整数，并传递浮点值做为双精度值。
Likewise, floating-point values are passed through the floating-point registers 1 through 13.
同理，浮点值是通过浮点寄存器1到13传递的。
For floating-point values only, both the integer register and the floating-point register will contain the float value in case the callee expects the value in the integer registers.
仅对于浮点值，被调用方希望使用整数寄存器中的值时，整数寄存器和浮点寄存器都将包含浮点值。
If you need to store floating-point values in a program, you must declare variables of type double, just as you previously had to declare variables of type int to write Add2Integers.
如果你需要在程序中存储浮点数，必须将变量类型声明为double，就像上面你写add2integers这个程序需要将变量声明为int型一样。
