Problem 44650. determine the sum of decimal part for given matrix

Hello, jamal hasoon. I completely agree with the preceding comment. Furthermore, it is very strongly recommended to write your own general solution code, to ensure compatibility of the inputs and the target solution in the Test Suite. —DIV

Alternatively, if you intend that users should round their results, then please include that instruction explicitly in the Problem Statement.  
Another point: please do not include so much sample code in the Solution Template that is seen by everybody.  
Lastly, it would be clearer to refer to the "decimal part" (or "fractional part"), rather than "fraction part".  
See Problem 44521 for more ideas.   —DIV

Problem statement and test cases have been modified.
