Ruby program to find the arccosine of the given value

Program/Source Code:

The source code to find the arccosine of the given value is given below. The given program is compiled and executed successfully.

# Ruby program to find the arccosine 
# of the given value

print "Enter value: ";
value = gets.chomp.to_f;  

result = Math.acos(value);
print "Arccosine is: ",result;

Output:

Enter value: 0.5
Arc Cosine is: 1.0471975511965979

Explanation:

In the above program, we read a value from the user using gets.chomp.to_f and got the arc cosine of the given value using Math.acos() function and printed the result.
