[GitHub] eric-haibin-lin opened a new issue #13220: Many operators don't work for integer type

eric-haibin-lin opened a new issue #13220: Many operators don't work for integer type 
URL: https://github.com/apache/incubator-mxnet/issues/13220
 
 
   Many operators implicitly cast data to float and return inaccurate results: 
   ```
   >>> mx.nd.array([50000001], dtype='int32')
   
   [50000001]
   <NDArray 1 @cpu(0)>
   
   >>> mx.nd.array([50000001], dtype='int32').floor()
   
   [50000000] ------------->  should be [50000001]
   <NDArray 1 @cpu(0)> 
   
   >> mx.nd.array([50000001], dtype='int32').round()
   
   [50000000] ------------->  should be [50000001]
   <NDArray 1 @cpu(0)>
   >>> mx.nd.array([50000001], dtype='int32').ceil()
   
   [50000000] ------------->  should be [50000001]
   <NDArray 1 @cpu(0)>
   >>> mx.nd.array([50000001], dtype='int32').trunc()
   
   [50000000] ------------->  should be [50000001]
   <NDArray 1 @cpu(0)> 
   ```
