Hi, can this sub be expressed in a simple mathematical function like int(8*$v) that returns exactly the same? 
sub quant { # input: float 0 to 1 inclusive
    my $v = shift;
    if ($v<1/9) { return 0 }
    elsif ($v<2/9) { return 1 }
    elsif ($v<3/9) { return 2 }
    elsif ($v<4/9) { return 3 }
    elsif ($v<5/9) { return 4 }
    elsif ($v<6/9) { return 5 }
    elsif ($v<7/9) { return 6 }
    elsif ($v<8/9) { return 7 }
    else { return 8 }
}
