+Note: this is actually a string operation, that is, in Redis there are not &quot;integer&quot; types. Simply the string stored at the key is parsed as a base 10 64 bit signed integer, incremented, and then converted back as a string.<h2><a name="Return value">Return value</a></h2><a href="ReplyTypes.html">Integer reply</a>, this commands will reply with the new value of <i>key</i> after the increment or decrement.
