safrooze opened a new issue #12478: Feature Request: randint
URL: https://github.com/apache/incubator-mxnet/issues/12478
 
 
   ## Description
   MXNet has no `randint` implementation and integer sampling can be both limiting and confusing to developers:
   * If using random_uniform with 'float32', the range is limited to 16.6M, beyond with there is no one to one mapping between float and int values.
   * My tests show that random_uniform with 'float64' seem to address the issue, but this is not obvious to most developers and it may be extra unnecessary precision to achieve the necessary accuracy.
   * It isn't very well known how to do proper random integer sampling using an underlying float sampling, i.e.:
   ```
   randint = cast(clip(random.uniform(low, high, shape), low, high-1), 'int32')
   ```  
   
   A `randint` operator implementation will solve all above issues.
