# Microsoft Calculator: What is the Exp Function Doing?

• Singularis
In summary, the conversation is discussing the use of Microsoft's calculator's Exp function and how it differs from the x^y function in calculating exponents. The Exp function multiplies the first number by 10 to the power of the second number, whereas the x^y function raises the first number to the power of the second number. The letter E in the Exp function stands for multiplying by 10 to the power of the second number.

When you use Microsofts calculator's Exp function it does not raise the number you enter exponenently it requestions another number and then does this

result = firstnumber * 10^second number

What is it doing?

Well if you want to calculate for instance $$2^5$$ you should use the $$x^y$$ function not the Exp function, the Exp function calculates $$2 \cdot 10^5$$.

I hope that I understood what you meant.

Is the Exp an exponention function? and is it to do with E?

Well this E stands for $$\cdot 10^{2nd nr.}$$, for example, 2E5 is the same as $$2 \cdot 10^5$$. So it is for multiply the first number with 10 to the power of the second number(after the E).

## 1) What is the Exp function used for in Microsoft Calculator?

The Exp function in Microsoft Calculator is used to calculate the exponential value of a given number. It raises the mathematical constant e to the power of the input number.

## 2) How do I use the Exp function in Microsoft Calculator?

To use the Exp function, open Microsoft Calculator and enter the number you want to calculate the exponential value for. Then, click on the "Exp" button to get the result.

## 3) What is the mathematical formula behind the Exp function?

The mathematical formula for the Exp function is e^x, where e is the mathematical constant approximately equal to 2.718 and x is the input number.

## 4) Can the Exp function be used for negative numbers?

Yes, the Exp function can be used for negative numbers. The result will be a decimal value between 0 and 1, as the exponential value of a negative number is a fraction.

## 5) How accurate is the result of the Exp function in Microsoft Calculator?

The accuracy of the result depends on the precision settings of Microsoft Calculator. The default precision is 32 digits, but it can be changed to up to 64 digits for more accurate results.
