In this program, we will read a number from the user using gets.chomp.to_f. Then we will find the value of e^value using the exp() function.

Program/Source Code

The source code to find the value of e^value using the exp() function is given below. The given program is compiled and executed successfully.

# Ruby program to find the value of 
# e^value using exp() function

print "Enter number: ";
num = gets.chomp.to_f;  

result = Math.exp(num);
print "Result: ",result;

Output

Enter number: -0.9
Result: 0.4065696597405991
