In Python, the exp() function is a mathematical function that calculates the exponential value of a number. It is part of the math module in Python, so you need to import the math module to use it.
Here’s the correct syntax for using the math.exp() function:
import math
result = math.exp(x)
In this syntax, x represents the number for which you want to calculate the exponential value. After importing the math module, you can use the math.exp() function to calculate the exponential value of x, and the result will be stored in the variable result.
Python exp() function example
Here’s an example that demonstrates the usage of math.exp():
import math
x = 2.5
result = math.exp(x)
print(result)
Output:
In this example, we import the math module. Then, we assign the value 2.5 to the variable x. The math.exp() function is used to calculate the exponential value of x, and the result is stored in the variable result. Finally, we print the value of result.
When you run this code, the output will be approximately 12.182493960703473. This means that math.exp(2.5) returns the exponential value of 2.5, which is approximately 12.182493960703473.
Remember to import the math module before using the math.exp() function.
