I would like to format a big int as a string with leading zeros. I'm looking for an example similar to this, but with Big:
I'm looking at source here.
But when I call:
m := big.NewInt(99999999999999)
fmt.Println(m.Format("%010000000000000000000","d"))
I see:
prog.go:10:22: m.Format("%010000000000000000000", "d") used as value
prog.go:10:23: cannot use "%010000000000000000000" (type string) as type fmt.State in argument to m.Format:
string does not implement fmt.State (missing Flag method)
prog.go:10:48: cannot use "d" (type string) as type rune in argument to m.Format
(I understand normally I can use m.String(), but zero padding seems to complicate this, so I'm looking specifically for some help on the Format method.)
Here's my playground link.
