为什么调用power方法报错
public class MyIntegerExt {
public Integer square(Integer self) {
return self * self;
}
public Double power(Integer self, Double exponent) {
return Math.pow(self, exponent);
}
public Boolean isOdd(Integer self) {
return self % 2 != 0;
}
}
//配置Integer扩展方法
Engine.addExtensionMethod(Integer.class, MyIntegerExt.class);
#set(num = 123)
#(num.square())
#(num.power(10))//报错
#(num.isOdd())
解决方法：
数字常量：123 456F 789L 0.1D 0.2E10 //1.double参数 Double power(Integer self, Double exponent) #set(num = 123) #(num.square()) #(num.power(10.0))或者#(num.power(10D)) #(num.isOdd()) //2.Integer参数 Double power(Integer self, Integer exponent) #set(num = 123) #(num.square()) #(num.power(10)) #(num.isOdd())
