Factorial (!)

This function obtains the factorials of a value that is zero or a positive integer.

Example: (5 + 3)! = 40320

Absolute Value Calculation (Abs)

When you are performing a real number calculation, this function simply obtains the absolute value.

Example: Abs(2 - 7) = 5



Random Number (Ran#)

This function generates a 3 digit pseudo random number that is less than 1.





(Ran#) 



Generate three 3-digit random numbers. The random 3 digit decimal values are converted to 3 digit integer values by multiplying by 1000.

Note that values shown here are examples only. Values actually generated by your calculator will be different.
