# `gno.land/p/moul/x/daily/humanize/v1`

**Human-facing number formatting** — `Bytes`, `Comma`, `Ordinal`, `Plural`,
`Blocks`, `Truncate`.

```go
import "gno.land/p/moul/x/daily/humanize/v1"

humanize.Bytes(1536)        // "1.5 KiB"
humanize.Comma(1234567)     // "1,234,567"
humanize.Ordinal(12)        // "12th"  — not "12nd"
humanize.Plural(2, "mouse", "mice")  // "2 mice"
humanize.Blocks(1234)       // "~1,200 blocks"
humanize.Truncate("ééé", 2) // "é…"
```

**v1 fixes `Comma` at the int64 minimum.** `v0` negated in `int64`, and `-n` on
`math.MinInt64` is `math.MinInt64`, so `FormatInt` emitted its own sign and the
`neg` branch prepended a second: `Comma(math.MinInt64)` returned
`--9,223,372,036,854,775,808`. The magnitude now goes through `uint64`.
`v0` stays resolvable for its existing importers.

**Integer-only, on purpose.** No floats anywhere: a rendered value that differed
between nodes would be a consensus bug, so the single decimal place in `Bytes`
comes from scaling by 10 and taking a remainder.

**Durations are in blocks, never seconds.** There is no wall clock on chain, so
"about 2 hours" is a lie dressed as precision. `Blocks` says `~1,200 blocks` and
lets the caller decide what that means on their chain — and rounds deliberately,
because false precision is worse than none.

`Ordinal` handles the teens (`11th`/`12th`/`13th`, not `11st`/`12nd`/`13rd`) —
the case naive implementations get wrong. `Truncate` counts **runes**, so
multi-byte text is never sliced mid-character.
