If <i>key</i> does not exist, a new key holding a hash is created. If <i>field</i> does not exist or holds a string, the value is set to 0 before applying the operation.</blockquote> |
| | 32 | <blockquote>The range of values supported by HINCRBY is limited to 64 bit signed integers.</blockquote><h2><a name="Examples">Examples</a></h2> |
| | 33 | Since the <i>value</i> argument is signed you can use this command to perform both increments and decrements:<br/><br/><pre class="codeblock python" name="code"> |
| | 34 | HINCRBY key field 1 (increment by one) |
| | 35 | HINCRBY key field -1 (decrement by one, just like the DECR command) |
