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.
If you typed it, then edit the cell and remove the negative sign. If it was calculated and you want to show only the numbe â¦ r without a sign, you can do one of two things: Multiply the results times -1.Use the ABS function to return the absolute value of the number. =ABS(2-3) will return 1 instead of -1.
