Indeed, for some gems, such as diamonds, the price per carat can increase exponentially as the gem size increases. Therefore, a 1 carat stone may cost $1,000 while a 2 carat stone may cost $4,000. This means that good quality sapphires and rubies in larger sizes tend to have a much higher price per carat.
Re: Convert positive # to negative. Hi, if you positive number is in A1, use the following formula to convert it to a negative number =A1*-1 Time values can not be negative. Microsoft MVP http://www.teylyn.com Twitter: http://twitter.com/IngeborgNZ. Microsoft MVP.
Now I can take the negative through the parentheses: â| â3 | = â(3) = â3. As this illustrates, if you take the negative of an absolute value, you will get a negative number for your answer. When typing math as text, such as in an e-mail, the pipe character is usually used to indicate absolute values. The pipe is probably a shift-key somewhere north of the Enter key on your keyboard.
