Floating Point Exception (core Dumped) Error In C

You should have x start at 2 instead. You should not use floating point here at all, since you only need integer operations. General notes: Try to format your code better. Focus on using a consistent style. E.g. you have one else that starts immediately after a if brace (not even a space), and another with a newline in between. Don't use globals unless necessary. There is no reason for q to be global. Don't return without a value in a non-void (int) function. share|improve this answer edited Sep 1 '10 at 6:30 answered Sep 1 '10 at 6:23 Matthew Flaschen 175k28368450 5 Addition: You get a Floating point exception since your computer does not have a special case for integer division by 0.

Yes, the square root of a negative number makes sense in the context of complex numbers, but there is no way to represent it in computers. These generally result is a +nan, -nan (Not a Number). Other operations that might lead to a NaN - 0/0, infinity/infinity, 0*infinity etc.Divide By Zero is raised when an operation of finite operands gives an infinite result. For Example - 1/0, log(0) etc. These generally result in +inf, -inf.IEEE Floating numbers have three components - the sign, the exponent, and the mantissa.The figure shows the layout for single (32-bit) and double (64-bit) precision floating-point values. The exponent, sign and mantissa together make up the number. There is a maximum and a minimum possible value for any of the layout.

In particular it happens to indicate that the issue involves something you may have attempted to do involving floating point. Without posting code, finding your bug is mere guesswork. Something like this may arise from trying to take the square root of a negative number, or attempting to divide by zero as examples. 0 Discussion Starter ekvenkatesh 8 Years Ago thank you dave for floating point exception your concern and your reply. 0 Naveen_ 5 Years Ago #include you to solve.) The exercise calls for calculating and displaying the average number of days a company's employees are absent with the use of three functions. One that asks for the number of employees. One that asks for the number of days missed by each employee, which you can use to find that total number of days missed. The third function calculates the average number of days missed per employee. I am working on a Mac with Mac OS version 10.6.2 and am using CodeBlocks 8.02. The program compiles without error but when I run it, it gives me an error after I enter in the first value. The error is "floating point exception." In researching floating point exceptions I found that it arises when your code is trying to something it is not allowed to do (like sqrt of a negative number). I cannot find where that error is in my code, however. I would appreciate any help in finding the error in my code. Thanks. Here is my code: #include
