#4826 closed defect (fixed)

Incorrect output when solving a negative factorial

Reported by: sarahmackey Owned by: sarahmackey
Priority: Unspecified by Maintainer Milestone: Unspecified
Component: Calculate Version: Unspecified
Severity: Minor Keywords:
Cc: castelliam, JoyeNettles Distribution/OS: Fedora
Bug Status: New

Description

When the user inputs a negative integer within the factorial function the result is just the number that is put into the function. The calculator prints it out and it appears that is the correct answer. However, the answer should not be defined because there is no factorial value of a negative integer.

for example:

input: fac(-5)
expected output: error or none
actual output: -5.00000000

Version: Using VirtualBox (firmware), Fedora Release 20 Heisenbug (Build), Sugar 0.103.2, Ubuntu 64-bit v.14.04.1
