包路径：android.database.Cursor
类名称：Cursor
方法名：getFloat

Cursor.getFloat介绍

[英]Returns the value of the requested column as a float.

The result and whether this method throws an exception when the column value is null, the column type is not a floating-point type, or the floating-point value is not representable as a float value is implementation-defined.
[中]以浮点形式返回请求列的值。
结果以及当列值为null、列类型不是浮点类型或浮点值不能表示为float值时，此方法是否引发异常是由实现定义的。
