# bin/set-u16-le Return a copy of `$bytes` with an unsigned 16-bit integer written at `offset` (little-endian). Byte strings are immutable — the original `$bytes` is unchanged. ## Syntax

[bin/set-u16-le $bytes $offset $value]

## Parameters - `$bytes` — byte string to copy and write into - `$offset` — 0-based byte offset - `$value` — value to write; clamped to the 16-bit range and truncated toward zero ## Examples

def buf [bin/set-u16-le [bin/zeros 2] 0 513]
[bin/u16-le-at $buf 0] # → 513
[bin/u8-at $buf 0] # → 1

## Returns New byte string. A negative or out-of-bounds offset returns `%Err{:message}`. ## See Also `bin/u16-le-at`, `bin/set-u16-be`, `bin/set-bytes`, `bin/bytes`
