summary: Increments the integer value of a field in a hash by a number. Uses 0 as
  initial value if the field doesn't exist.
syntax_fmt: HINCRBY key field increment
title: HINCRBY
---
Increments the number stored at `field` in the hash stored at `key` by
`increment`.
If `key` does not exist, a new key holding a hash is created.
If `field` does not exist the value is set to `0` before the operation is
performed.

The range of values supported by `HINCRBY` is limited to 64 bit signed integers.

## Examples

Since the `increment` argument is signed, both increment and decrement
operations can be performed:

{{% redis-cli %}}
HSET myhash field 5
HINCRBY myhash field 1
HINCRBY myhash field -1
HINCRBY myhash field -10
{{% /redis-cli %}}
