   ### Search before asking
   
   - [X] I had searched in the 
[issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no 
similar issues.
   
   
   ### Description
   
   Doris can support type conversion for float text to float, and float to int, 
but cannot support type conversion for float text to int.
   See below,

   And in mysql, float text can be converted to signed integer.

   So I think the float text conversion to int should be supported in Doris.
   
   ### Solution
   
   support cast('float text' as int)
