This shows how you don't understand the promotion of datatypes.

Expression1: Since * and / have the same precedence the first expression is evaluated left to right, the 1 gets promoted to $1: $8192 * $1 = $8192. the 8192 gets promoted to $8192: $8192 / $8192 = $1.

Expression2: 1 / 8192 = 0.0001220703125 which gets promoted to $0.0001, $8192 * $0.0001 = $0.8192

I don't particularly care if you reply. But it won't stop me from posting counterpoints to your messages.
