This simple calculator is still under construction.
Enter the expression you want to evalaute below. You can use +, -, *, /, and paranthesis. For e^x, use exp(x). For ln(x), use ln(x). For x^y, use pow(x,y). For sin(x), use sin(x). Similar thing applies to tan(x) and cos(x). For sqrt(x), use sqrt(x). For x^2, use sqr(x). For abs(x), use abs(x). For floor(x), use floor(x). For, ceiling(x), use ceil(x). For Pi, use pi(). For the greatest common divisor of a and b, use gcd(a,b). For the least common multiple of a and b, use lcm(a,b). For n!, use factorial(n). For round(x), use round(x).
Enter the expression you want to evaluate in the box below. Then press on the "EVALUATE" button. The result will show up in the box below the "EVALUATE" button.
For short "single" calcualtions and for CONVERSIONS from one number system to another, you can use the following.
