1·The memory space of a float or double value is limited, so some values cannot be represented.

浮点或者双精度浮点的内存空间是限定了的，所以某些值不能被表示。

2·These classes allow the various geometric shapes to be constructed with coordinates of either double or float precision.

这些类允许各种几何图形建立在双精度或浮点精度的坐标系上。

3·If the argument is zero, then the result will be -127 for a float and -1023 for a double.

如果参数为0，则对应的浮点数和双精度数的结果分别是- 127和- 1023。

4·C-89 data types (include signed and unsigned) short, int, long, long long, float, and double.

C - 89数据类型(包括有符号和无符号)short、int、long、long long、float和double。

5·The next two—float and double—represent floating-point numbers, again with different dynamic ranges.

随后的两种——float和double，代表了浮点型数，同样具有不同的动态范围。

6·If the argument is NaN or Inf, then the result will be 128 for a float and 1024 for a double.

如果参数为NaN或Inf，则对应的浮点数和双精度数的结果分别是128和1024。

7·The Mandelbrot set is infinitely deep and complex at all scales, but a float or a double can go only so deep before losing the ability to distinguish adjacent points.

Mandelbrot集合在各个级别上都是非常细微和复杂的，但是float或double可以在失去区分相邻点的能力之前达到这个细微的级别。

8·The left and right values in the macro must be of the same type—float or double.

这个宏中的左值和右值必须是相同类型的 — 即要么是 float，要么是 double。

9·So I'm printing out line by line a char will take out some number of bytes; a double, some number of bytes; a float; and an int.

所以我将要逐行地打印出一个char类型占了几个字节，一个double类型要占了几个字节，还有float和int类型。

10·There's a float and a double version to maintain the type.

一个float和一个double版本可用来维护这种类型。
