How does this one work:

Question

printf("Pi = %8.5f", 3.14159);
/* Pi = 3.14159 */

I thought the 8 in there specifies the minimum width, in which case wouldn't the input of 3.14159 be too short?

Answer 1

With 8 you specify the absolute width. If your number is shorter, it will be right-aligned on a space of 8. The minimum means, that the number will not be truncated, should it be longer.

Answer 2

i still cant understand

output is
Pi = 123456789.12

Answer 3

Check these...

printf("Pi = %08.2f \n", 9.12345 );

In 08.5f
0 is filled in to stretch value atleast length of 8 digits including dot.

Ex: observe output...

printf("Pi = %08.2f \n", 3.1 );

printf("Pi = %08d \n", 3 );

printf("Pi = %08.2f \n", 12.12345 );
