What is the difference between "%s" and "%d"?

What is the difference between "%s" and "%d"?

[Marcin Borkowski]

Hi all,

consider two forms:

(format "%d" int)

and

(format "%s" int)

Assuming that `int' is bound to an integer, is there any difference
between the two?

TIA,

No, but for a number-%-sequence there are many flags available to
customize how it is printed.

,----[ C-h f format RET ]
| The argument used for %d, %o, %x, %e, %f, %g or %c must be a number.
| Use %% to put a single % into the output.
| 
| A %-sequence may contain optional flag, width, and precision
| specifiers, as follows:
| 
|   %<flags><width><precision>character
| 
| where flags is [+ #-0]+, width is [0-9]+, and precision is .[0-9]+
