What can I do to display the correct output?

Question

What is wrong with the code when I declare data type as float, initialize a variable with a float number e.g 300.653465 but when I apply the printf function it displays only 300.6535 or it adds unknown digits like 300.653503

Answer 1

Use double in order to get more decimals.

#include <stdio.h>

int main(void) {
double x = 300.653465; //has 6 decimals

printf("value of x: %.6f", x); // "%.6f" will make it show up to 6 decimals

return 0;
}

Answer 2

Take a look at why floating point values stored in variables, or in computer systems in general, can be inaccurate.
