Hi,
first of all: mapserver 5 rocks. THX.
I have one question: I found in the history.txt that the "modulus"
operator is supported by expressions. Now I am uncertain what is
meant:
- "modulus" the absolute value of a number without a sign or
- "modulo" the rest of an integer division, usually expressed with the
operator "%"
When i looked in mapparser.y i found this line:
345: math_exp '%' math_exp { $$ = (int)$1 * (int)$3; }
This looks like the modulo operator is defined, but the calculation is
not modulo.
Can someone shed some light on this?
I am trying to classify isolines with the expression ([iso-value] %
10) and it should draw all iso lines that are dividable by 10 without
a rest, e.g. for giving them a thicker line width. But it nevertheless
draws all lines.
Cheers, Michael
