Why does a C floating-point type modify the actual input of 125.1 to 125.099998 on output?

Question

I wrote the following program:

 #include
    int main(void)
    {
     float f;
     printf(\"\\nInput a floating-point no.: \");
     scanf(\         


        

Answer 1

Because its the closest representation of 125.1 , remember that single precision floating point are just 32 bits.
