I am getting mixed answers on my research here.
Can someone verify that the Redis Server can only store representation of any numerical values?
For instance, if I use a Java client (Jedis) with a double type in lpush, do I need to convert it to the equivalent of a string type before sending to Redis?
Or is there a way to I can send over an actual numeric type like a double? If so, is there any example code on how to accomplish this?
Thanks
In Redis, we have the advantage of storing both strings and collections of strings as values. A string value cannot exceed 512 MB of text or binary data. However, it can store any type of data, like text, integers, floats, videos, images, and audio files.
Redis stores integers in their integer representation, so for string values that actually hold an integer, there is no overhead for storing the string representation of the integer.
Redis stores everything in string or in its string representation. Even functions like INCR work by first parsing it into INTEGER then performing the operation
Note: this is a string operation because Redis does not have a dedicated integer type. The string stored at the key is interpreted as a base-10 64 bit signed integer to execute the operation.

And w.r.t Jedis; looking at the source i don't think it supports anything else other than strings
