kOther Functions

x!, Abs(, Ran#, nPr, nCr, Rnd(

The x!, nPr, and nCr functions can be used in the CMPLX Mode, but complex number arguments are not supported.

A Factorial (!)Syntax: {n}! ({n} must be a natural number or 0.)Example: (5 + 3)!(5+3) ( 5 +3 ) !

A Absolute Value (Abs)

When you are performing a real number calculation, Abs( simply obtains the absolute value. This function can be used in the CMPLX Mode to determine the absolute value (size) of a complex number. See “Complex Number Calculations” on page 34 for more information.

Syntax: Abs({n})
Example: Abs (2 –	7) = 5
		1)(Abs)2-7)E	Abs ( 2	–7 )
				5

A Random Number (Ran#)

This function generates a three-decimal place (0.000 to 0.999) pseudo random number. It does not require an argument, and can be used the same way as a variable.

Syntax: Ran#Example: To use 1000Ran# to obtain three 3-digit random numbers.
