You are confused.
For more information, please read the man pages on mkfs and fdformat. 
 Also man on mkdosfs and mkfs.msdos.

mkfs formats the filesystem and has many options to tell it size and 
filesystem type, plus some readily available tailored options are 
already on the system. (mke2fs, mkdosfs, among many others)

fdformat does the low level format of the floppy disk, and does NOT 
actually create the filesystem as far as I can find.

When using fdformat you must then follow it with mkdosfs or similar to 
create the filesystem.
