HINCRBYFLOAT

Increments the value of a field in a hash stored at key by the given increment. If the field does not exist, it is set to increment. If the key does not exist, a new hash is created with the field set to increment. The increment can be a positive or negative floating-point number.

Syntax​

HINCRBYFLOAT key field increment

Details​

  • Available since: 2.6.0
  • Time complexity: O(1)
  • ACL categories: @write, @hash, @fast

Example​

Assume we have a hash called myhash with a field "balance" initialized to 100.5:

HSET myhash balance 100.5

Now, let's increment the value of "balance" by 25.75:

HINCRBYFLOAT myhash balance 25.75

This will output:

"126.25"
