[kw-pm] sprintf Issue

[Robert Pike]

Is there a limitation on trying to format numbers using sprintf? I'm trying to format a number like 10005000035, so as to have leading zeros up to a total length of 20 such as this :
       
print "Formatted : " . sprintf("%020d", $processId);  # processId is equal to 10005000035

Is there a problem with this approach or a better way of doing it? Thanks in advance for any feedback.
