Totalview® User Guide : PART II Debugging Tools and Tasks : Chapter 10 Examining Arrays : Examining and Analyzing Arrays : Filtering Array Data Overview : Filtering by Comparison
Filtering by Comparison
The simplest filters are ones whose formats are as follows:
operator value
where operator is either a C/C++ or Fortran-style comparison operator, and value is a signed or unsigned integer constant or a floating-point number. For example, the filter for displaying all values greater than 100 is:
> 100
The following table lists the comparison operators:
 
Comparison
C/C++ Operator
Fortran Operator
Equal
==
.eq.
Not equal
!=
.ne.
Less than
<
.lt.
Less than or equal
<=
.le.
Greater than
>
.gt.
Greater than or equal
>=
.ge.
Figure 156 shows an array whose filter is < 0. This tells TotalView to display only array elements whose value is less than 0 (zero).

If the value you are using in the comparison is an integer constant, TotalView performs a signed comparison. If you add the letter u or U to the constant, TotalView performs an unsigned comparison.
