Re^2: To hex EXPR or 'EXPR' is my question

[biohisham]

Thanks folks, this made me see this confusion under another light, it seems after all that perl interprets EXPR so quickly that both hex and oct become useless anatomical-appendices (metaphorically speaking) if EXPR was passed preceded by '0x' in a string, not trying to make a generalization here rather than a mere observation and not trying to dig myself a hole by including the '0'-preceded EXPRs either (octals may have another behavior I guess), so correct me if I am wrong with regard to the following:

print 0xCA;
202
print hex '0xCA'; #<-- what use does hex have?
202
print oct '0xCA'; #<-- what use does oct have?
202

The issue is, what can be gotten out of this behavior is brain-bombing and to quote EXPR or not warrants someone being absolutely aware of how they're going about it since the docs and faqs are kinda shallow when it comes to making us aware of this..What do you monks think??

Interpreting strings that are read from external sources:

print 'deadbeef';;
deadbeef

print '0x'.'deadbeef';;
0xdeadbeef

print 0+ '0x'.'deadbeef';;
Argument "0x" isn't numeric in addition (+)
0deadbeef

print hex 'deadbeef';;

print '77777777';;

print '0'.'77777777';;
077777777

print 0+'0'.'77777777';;
077777777

print oct '77777777';;
