Not certain, no :)

But I would imagine it would be a mess if they didnt.
The to Int functions are probably a bad example due to there being different size Ints (32 and 64 for example)
But something like CStr and Convert.toString(), if these did different things.
eg

Convert.toString(100.567) => "100.567"
CStr(100.567) => "101"   // As seen in FP STR() function

Then it would become a very easy way to break things :)
