What is %f in C language?

‘%f’: Print a floating-point number in normal (fixed-point) notation. See Floating-Point Conversions, for details.

How do you convert a decimal number to a decimal?

Step 1 − Divide the decimal number to be converted by the value of the new base. Step 2 − Get the remainder from Step 1 as the rightmost digit (least significant digit) of new base number. Step 3 − Divide the quotient of the previous divide by the new base.

What does %2d mean in C?

It specifies the minimum width that the output should be. If the width specified is more than the size of the output itself (the opposite of your case), then the difference between the length of your output and the width specified will be printed as spaces before your output.
