I would suggest one small change, just to make clear that the number's name "e" actually derives from the name "Euler": EXP(number) - Returns e raised to the power of the given number. The constant e stands for the Eulerian number, which is also the base of the natural logarithm. It equals 2.71828182845904..., therefore, the function used with "number" being 1, =EXP(1), would return 2.71828182845904... Guido
