 1.Create a project;
 2.oc create -f hello-deployment-1.yaml;
 3.Go to Applications -> Deployments -> <Deployment name> page -> Actions -> Set Resource Limits；
4. Set Memory to 900.9 MB；
5. Save;
6. Open Set Resource Limits again to check, and try to modify again.

Actual results:
5. Save successfully;
6. Display “900900kB”, but memory frame turn red and prompt error memory "can not be less than 250 MiB. Memory limit total for all containers is less than pod minimum (250 MiB)." Button "save" is not available.

Expected results:
900900kB is a valid value. No error message is displayed, button ‘save’ is available.

Additional info:
1. When  you input 900900000 kB, button ‘save’ become available,Maybe the unit shoud be B, not KB.
2. The convert between MiB to mB is correct.
