NOTE : The correct decimal places of double is utilized by the code so no problem as such, I just want to see it via printf.-lc -lrdimon -u printffloat. These two changes gave me functional printf() what displayed numbers instead of just showing "f" in place of number. Programming.The standard math functions take a double by default (for example, sin() takes a double if you want a float youve got to use sinf()).
