Don't think - or else you end like me asking questions! And my next
question is: Which routine is the fastest when you have a 80x87?
a) a := 22/7; b) a := 22/7
a := a + 1; b := 0;
b := 0; for c := 1 to 1000 do
for c := 1 to 1000 do b := b + c;
b := b + c; a := a + 1
It depends of the implementation of course, but does anybody out there
know a compiler/library that make b) faster than a) because it dosn't
wait for the calculation of the variabel a to finish before it has to
use it (a := a + 1)?
