irr()
Catalog >
CFList is a list of cash flow amounts after
the initial cash flow CF0.
CFFreq is an optional list in which each
element specifies the frequency of
occurrence for a grouped (consecutive) cash
flow amount, which is the corresponding
element of CFList. The default is 1; if you
enter values, they must be positive integers
< 10,000.
Note: See also mirr(), page 113.
isPrime()
Catalog >
isPrime(Number) ⇒ Boolean constant
expression
Returns true or false to indicate if number
is a whole number ≥2 that is evenly
divisible only by itself and 1.
If Number exceeds about 306 digits and has
no factors ≤1021, isPrime(Number) displays
an error message.
If you merely want to determine if Number
is prime, use isPrime() instead of factor(). It
is much faster, particularly if Number is not
prime and has a second-largest factor that
exceeds about five digits.
Note for entering the example: For
instructions on entering multi-line program
and function definitions, refer to the
Calculator section of your product
guidebook.
Function to find the next prime after a
specified number:

isVoid(Var) ⇒ Boolean constant
expression
isVoid(Expr) ⇒ Boolean constant
