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.

The Microsoft Excel MIN function returns the smallest number in a list of arguments. If the smallest number is zero (0), the function returns zero. To return the smallest number greater than zero, enter the following array formula. where A1:A10 represents the range of the numbers. This returns an array of a single value with the smallest positive number. NOTE: To enter an array formula in Excel for the Macintosh, press COMMAND+RETURN.
