Look, learn the language first, /then/ construct hypothetical problems. If you want a division of two integers to yield an integer always, you have the four subtly different operators that does precisely this. Using the general division operator is Just Plain Wrong. Quit whining about non-problems. | In addition and expression that evaluates to a float in one implementation | might return a rational in another, which could lead to compatibility | problems. Do you have any examples of this? | I don't know what other things somebody might come up with, but I guess you | get the idea. I see that you are happy constructing hypothetical problems, but you have so far not provided the connection from them to reality. This is actually far more relevant than anything you can come up with in a vacuum. | I'd be interested to know what the rationale for these decisions was. I believe this is part of the public record. I have not checked this part of the specifications sufficiently closely, and even misremembered the issue on complex, but I believe the story on complex numbers have been covered sufficiently well in CLtL1 and CLtL2. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
