Package fmt

Package fmt implements formatted I/O with functions analogous to C's printf and scanf.
The format 'verbs' are derived from C's but are simpler.

Useful Functions:

Errorf(format string, a ...any) error
Fprint(w io.Writer, a ...any) (n int, err error)
Printf(format string, a ...any) (n int, err error)
Sprintf(format string, a ...any) string

Common format verbs:

%b      integer (base 2)
%c      character (Unicode code point)
%d      integer (base 10)
%o      integer (base 8)
%q      quoted string "abc" or rune 'c'
%s      string
%T      type of any value
%v      the value in a default format
%+v     structs: adds field names
%#v     a Go-syntax representation of the value
%%      literal percent sign (no operand)

Decimal numbers:

%f      precision 6 (default)
%.f     precision 0
%.2f    precision 2
