what I am refering to is as follows:-
If we wish to round to 3 DP.... then normal rounding is as follows
1.64354 => 1.644
If we were to round down to 3Dp... then it would be as follows
1.64354 => 1.643
I believe, this is called ROUND_HALF_DOWN in Java.

tcl has both "%" for integer and "fmod(x,y)" for floating point number. So
you could write a small procedure based on either of them to round up or down
easily.
