1. Step 1: Insert User Form. Press ALT + F11 key to open the VBA Editor.
2. Step 2: Design Userform. From the toolbox of the userform, insert two label boxes and enter the text, as shown below.
3. Step 3: Code. We are done with the VBA login user form design part.

## What is the difference between log and ln?

The difference between log and ln is that log is defined for base 10 and ln is denoted for base e. A natural logarithm can be referred to as the power to which the base ‘e’ that has to be raised to obtain a number called its log number. Here e is the exponential function.

## What is log E in Excel?

The LN function returns the natural logarithm of a given number. The natural logarithm is equivalent to log base e of a number, where e is Euler’s number, a mathematical constant with the approximate value 2.71828182845904.

The natural logarithm is the logarithm to the base e. The constant e is approximately 2.718282. You can calculate base-n logarithms for any number x by dividing the natural logarithm of x by the natural logarithm of n as follows: Logn(x) = Log(x) / Log(n)

## How does debug print work in VBA?

Debug. Print is telling VBA to print that information in the Immediate Window. This can be useful when you want to see the value of a variable in a certain line of your code, without having to store the variable somewhere in the workbook or show it in a message box.

Enable Microsoft Internet Controls This macro requires Microsoft Internet Controls to be enabled. In the VBA Editor window (Alt+F11) go to Tools > References > Check next to Microsoft Internet Controls and hit OK.

## Can a logarithm be a negative number in Excel?

If the argument is not explicitly specified, the logarithm is considered decimal (that is, the base is 10). Although the result of calculating the LOG function may be a negative number (for example, the function =LOG (2,0.25) returns a value of -0.5), the arguments of this function must be taken from a range of positive values.

## Is the natural logarithm related to the EXP function?

The natural logarithm is related to the EXP function. In EXP, we get the value if a base number is raised to an exponential number, and in logarithm, we need to know the exponential number to get the desired number. Recommended Articles. This has been a guide to LN in Excel.
