Features and Help

• Most keys are like a regular calculator.
• There are 10 registers (STO 0, ... STO 9).
• The stored values are recovered by using RCL n.
• Fact calculates the factorial of a number even if this number is not an integer. For example, Fact(5) = 120; Fact(0.5) = 0.8862; Fact(-0.5) = 1.7724.
• Gamma is the Gamma function.
• G is Catalan's constant.
• Phi is the golden number 1.618...
• gamma gives you Euler's constant: 0.577215664...
• nCk is the binomial coefficient. n is a real number. For example, 5 nCk 2 = 10; 3 nCk 5 = 0; -0.5 nCk 5 = 0.24609...
• Floor Just a reminder. Floor(x) means the biggest integer less or equal than x.
• Ceiling Just a reminder. Ceiling(x) means the smallest integer greater or equal than x.
• Fn gives the nth Fibonacci number.
• mod is the module operation. For example, 3 mod 5 = 3; 8 mod 2 = 0.
• Accuracy gives you the number of digits in the decimal place, up to 9, you want to be displaye on. The default number of digits in the deciaml place is 4.
• Notice the buttoms to work with radians or degrees.
• Illegal operations are not always reported. However, depending on your browser, you can figure out that there's some problem because you'll see strange symbols on your little screen.
• The calculator is not fully tested. If you find some mistake, please e-mail me. That will be greatly appreciated.
