How to check diff between two files

Shell Programming and Scripting
1

File 1 contains:
RECT 0 0 98 90
RECT 0 0 100 101

File 2 contains:
RECT 0 0 98.0 90.0
RECT 0 0 100 101

If I do, sdiff -s <file1> <file2>, it shows difference of first line.

But as the first line is algebrically equal, i want a command which shows no difference. i.e. it gives no difference when the numeral values are algebrically same.
