printf %f with only 2 numbers after the decimal point?

Question

In my printf, I need to use %f but I\'m not sure how to truncate to 2 decimal places:

Example: getting

3.14159

Answer 1

I suggest to learn it with printf because for many cases this will be sufficient for your needs and you won't need to create other objects.

double d = 3.14159;     
printf ("%.2f", d);

But if you need rounding please refer to this post
