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。
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。
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。
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。
Watch for the use of float and double type.

Recall from previous articles that Scala treats functions as values, just as it does any other value in the language, like Int, Float, or Double.
回忆前几期文章，Scala将函数作为值处理，就像处理语言中的其他值一样，例如Int、Float或Double。
If you specify the precision to be a value of 23 or less, the FLOAT (val) is equivalent to a REAL; if the precision is between 24 and 53, the FLOAT (val) is equivalent to a DOUBLE.
如果指定了小于等于23的精度值，FLOAT (val)就等价于REAL；如果精度在24和53之间，那么FLOAT (val)等价于DOUBLE。
