			==Bug in Multiplan==
			In 1984 TI confirmed a bug in the SQRT (square root) function which could not be fixed but TI provided a multiple-cell workaround.

			"If a square root is taken of a number less than one, AND contains an ODD number of zeros before the first significant digit (for example 0.01 or 0.000123), Microsoft Multiplan will calculate the square root incorrectly by a factor of ten.
			For example SQRT(0.01) is calculated as 1.0 instead of 0.1, and SQRT(0.000123) is calculated by Microsoft Multiplan as 0.110905 instead of 0.0110905.

			The fix was to use two intermediate cells to test if the number you wanted a square root of fell into the error range, and if so, divide the result by ten.
