### Overview

Raising an element to a particular exponent power is a common practice in arithmetic. When conducting an arithmetical computation, we may need to know when to get the value of a number to a particular exponent. We can easily achieve this considering two values in Euphoria, using the power function.

### The power function

This function is used to carry out an exponentiation operation. The power() function raises a value, the base, to the power of another value, the exponent, and returns the output of such an operation.

### Syntax

power(baseValue, exponentValue)


### Parameters

• baseValue: This represents the value of the base which will be exponentiated.
• exponentValue: This is the value of the exponent, which is the power that the base will be raised to.

### Return values

This function will return an exponentiated object value.

### Common errors

The following actions can cause this function to throw an exception error.

• When a base value that is negative is raised to a value that is not an integer, it causes an error because the result is undefined.

• Raising 0 to a negative power causes an error because it is similar to saying that zero is divided by something, which is mathematically erroneous.

• Doing something like Power(0,0) is an illegal operation because zero values do not really represent unique quantities.

### Code

Now that our understanding of this function is clear, let’s see some code examples.


--so let just go straight and print  to screen some power output
puts(1,"This is the output of 2 to power of 5 : ")
print(1,power(2,5))
puts(1,"\n Result of 2 to power of 10, and 5 power 2 : ")
print(1,power({2,5},{10,2}))
puts(1,"\n This is the output of 4 to power of -3 : ")
print(1,power(4 ,-3))


### Explanation

Several instances where different values are raised to the power of different exponents are showcased in the code above.

• In line 2, we see a simple comment.
• In lines 3, 5 and 7, the puts() function prints some new lines and comments to the screen.
• Lines 4, 6, and 8 contain the print() function, which prints the output to the screen after the power() operation is carried out on some variables.
