DECRBYFLOAT why not?

[topilski]

Hi, Redis have incrbyfloat but i didn't find decrbyfloat docs. Is this command exists?

[mgravell]

It is redundant since you can just incrbyfloat a negative. Yes, the same is true of decrby, but: that isn't by itself a good reason to *keep* knowingly adding redundant methods.

Hi @mgravell , thank you for reply, may be in this case need to remove decrby?

[antirez]

@topilski yes, the idea is to deprecate it at some point... It's completely useless AFAIK.

[antirez]

(but it's there since Redis 1.0 -- back then the idea was, that given that we had INCR and DECR, when INCRBY was introduced, it was odd to lack the symmetrical. Later the community started to develop and urgency about avoiding adding new commands, so the float version comes without such symmetrical command. Unfortunately backward compatibility is great but has such side effects of not removing certain errors).

@antirez thank you for clarification, i think we can close this issue. Also please update docs for TYPE command, now Redis have new type 'stream' , thank you for the good work!

[antirez]

Thanks! TYPE command updated.
