Question: Why does the string 0 become -0?

Hello!

If I wirite in an algorithm in MapleTA 9.5 the number 0, and later use it (for export to latex), it becomes negative, but not if I pass through Maple:

 

$null=0;
$zero=maple("0");
$nullstring="$null";
$zerostring="$zero";

results in:

null 0
zero 0
nullstring -0
zerostring 0

 

Why, and what can be done without passing through Maple?

 

Best,

Jan
