number |

Returns
The natural logarithm of number. Usage
The return value is single-precision for an integer, currency, or single-precision numeric expression; double precision for a long, variant, or double-precision numeric expression. Example
This example uses the Log function to determine which number is larger: 999^1000 (999 to the 1000th power) or 1000^999 (1000 to the 999th power). Note that you cannot use the exponent (^) operator for numbers this large. Sub Button_Click Dim x Dim y x = 999 y = 1000 a = y * (Log(x)) b = x * (Log(y)) If a>b then "999^1000 is greater than 1000^999" Else "1000^999 is greater than 999^1000" End If End Sub
