The procedure for filtering an array is simple: select the Filter field, enter the array filter expression, and then press Enter.
TotalView updates the Variable Window to exclude elements that do not match the filter expression. TotalView only displays an element if its value matches the filter expression and the slice operation.
If necessary, TotalView converts the array element before evaluating the filter expression. The following conversion rules apply:
|
If the filter operand or array element type is floating point, TotalView converts the operand to a double-precision floating-point value. TotalView truncates extended-precision values to double precision. Converting integer or unsigned integer values to double-precision values might result in a loss of precision. TotalView converts unsigned integer values to nonnegative double-precision values.

|
If the filter operand or the array element is an unsigned integer, TotalView converts the operand to an unsigned 64-bit integer.
|
|
|
If both the filter operand and array element are of type integer, TotalView converts the values to a 64-bit integer.
|
TotalView conversion operations modify a copy of the array’s elements—conversions never alter the actual array elements.
To stop filtering an array, delete the contents of the Filter field in the Variable Window and press Enter. TotalView then updates the Variable Window so that it includes all elements.
