Redis INCRBYFLOAT – How to increment a floating point value in redis

1 month ago Lalit Bhagtani 0

In this tutorial, we will learn about how to increment the string representing a floating point value stored at a key in redis datastore. For this we will use a COMMAND – INCRBYFLOAT in redis-cli. 

This command is used to increment the string representing a floating point number stored at the key by the specified value. If the key does not exist, it is first created and set to 0 before performing the increment operation. If the key exist but value stored at the key is of wrong datatype ( not string datatype ) or contains a string value that can not be represented as a double precision floating point number then error is returned. The syntax of redis INCRBYFLOAT command is as follows :-

Syntax :-

redis host:post> INCRBYFLOAT <keyname> <increment>

Output :-

- (string) reply, representing the value of the key after the increment operation.

Example :-
