Java类型Float&&Double

package study;

public class testFloatDouble {
public static void main(String[] args) {
float f = 0;
double d = 0;
for (int i = 0; i < 10; i++) {
f += 0.1;
d += 0.1;
}
System.out.println("float类型： f = " + f);
System.out.println("double类型： d = " + d);
}
}

结果如下：

float类型： f = 1.0000001
double类型： d = 0.9999999999999999
