关于#iC语言#的问题，如何解决？

Question

#include<stdio.h>
int main()
{
float income, tax;
printf("Enter the income of single resident: ");
scanf("%f", &income);

if (income<=750.00f)
    tax = income * .01f;
else if (income<2250.00f)
    tax = 7.50f + (income-750.00f)  * 0.02f;
else if (income<3750.00f)
    tax = 37.50f + (income-2250.00f) * 0.03f;
else if (income<5250.00f)
    tax = 82.50f + (income-3750.00f) * 0.04f;
else if (income<7000.00f)
    tax = 142.50f + (income-5250.00f) * 0.05f;
else
    tax = 230.00f + (income-7000.00f) * 0.06f;
printf("Tax is:$%.2f\n",tax);
return 0;

}
其中将0.02f换成.02f有区别吗？本人没有试出来。求专家解答

Answer 1

0.02f就是.02f啊
