类名称：Helper
方法名：degreeToInt

Helper.degreeToInt介绍

[英]Converts into an integer to be compatible with the still limited DataAccess class (accepts only integer values). But this conversion also reduces memory consumption where the precision loss is acceptable. As +- 180° and +-90° are assumed as maximum values.
[中]转换为整数以与仍然有限的DataAccess类兼容（仅接受整数值）。但在精度损失可以接受的情况下，这种转换还可以减少内存消耗。假定+180°和+90°为最大值。
