## FibGen(x, y, numSeq)

##### Last updated June 26, 2002

Version: 1 | Requires: CF5 | Library: MathLib

Description:
Returns the Fibonacci sequence to n places given a starting point of x and y (each integer is the sum of the two previous integers). Note that the function will also calculate the sequence for non-Fibonacci numbers. Based on FibCalc() by Phillip B. Holmes (pholmes@mediares.com).

Return Values:
Returns a comma-delimited list of numbers.

Example:

``````<cfoutput>
#FibGen(0,1,10)#<BR>
#FibGen(1,1,10)#
</cfoutput>
``````

Parameters:

Name Description Required
x First number in the sequence. Yes
y Second number in the sequence. Yes
numSeq Number of elements to generate for the sequence. Yes
