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 215 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.
