浮动不起作用，否则else语句（c）

Question

Whenever I try to use a float value in this IF ELSE statement it gives me 0 or an incorrect answer. I have used INT for the rest of the code and the rest works fine. This is the first time I have used float in the code and now it's not giving me the answer I want.

Can you please tell me what am I doing wrong?

float interestrate;

    if (month < 49)
    {
        interestrate = (0.063);
    }
    else if (salary <= 25000)
    {
        interestrate = (0.033);
    }
    else if (salary > 45000)
    {
        interestrate = (0.063);
    }
    else
    {
        interestrate = (0.033+(salaryabovethreshold*0.0000015));
    }

    printf("Interest Rate: %d \n", interestrate);

Answer 1

The %d format specifier is for int s, not float s. Try %f , %e or %g or %a for floating-point types.
