'max' aggregate not working for columns with only negative numbers

[aploiicostelMember]

The ‘max’ aggregate value is reported correctly only if there’s at least one positive number in the column, otherwise it’s always 0.

for column: [-4 -11 -1 -2 -7 -7 -7 -5 -11 -7] => max = 0
for column: [ 4 -11 -1 -2 -7 -7 -7 -5 -11 -7] => max = 4
for column: [ 4  11  1  2  7  7  7  5  11  7] => max = 11

Tested with jqwidgets-ver3.0.2/demos/jqxgrid/aggregates.htm and all numeric types of datafield (int, number, float):
