IsCloseTo.closeTo介绍
[英]Creates a matcher of Doubles that matches when an examined double is equal to the specified operand, within a range of +/- error. For example:
assertThat(1.03, is(closeTo(1.0, 0.03)))[中]创建一个双精度匹配器，当检查的双精度等于指定的operand，且在+/-error范围内时匹配。例如：
assertThat(1.03, is(closeTo(1.0, 0.03)))代码示例
