Syntax: Lg ( number )


numberAny expression that resolves to a positive numeric value or a field containing a numeric expression.

Data type returned: Number


Returns the base-2 logarithm of number. Negative values for number return an error.

The base-2 logarithm (often called the binary logarithm) of a number is the power of 2 that you would need to generate the number. Thus, if 2^x = y, then Lg(y) = x. The value returned by the Lg() function is increased by 1 every time that x is doubled.


 Lg (1) = 0

 Lg (2) = 1

 Lg (32) = 5
