Well, not utterly useless, only *reasonably* useless, because (as
pointed out by someone) it computes sin0 (my mistake!) whereas it was
meant to change x in between, so the reason why (on systems where gcc
did NOT optimize the loop away) it was so fast on Linux because FSIN
in special cases of arguments (such as 0) is many times faster than in
general case, so the numbers I gave were *valid* numbers but not very
useful because they referred to the special case of sin(0)=2E

Thanks for your reaply=2E

I like this =2Esignature too=2E=2E=2E

PS=2E Don't read my =2Esignature - it is automatically generated and I
