The parens around -50 are necessary. Is there a more elegant way to write it?
Without the parens, I don't understand what the compiler sees it as, based on the error message. How does the compiler parse it in that case?
It most likely sees it as the binary minus rather than the unary minus. /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus@therning.org jabber: magnus@therning.org twitter: magthe http://therning.org/magnus The results point out the fragility of programmer expertise: advanced programmers have strong expectations about what programs should look like, and when those expectations are violated--in seemingly innocuous ways--their performance drops drastically. -- Elliot Soloway and Kate Ehrlich
