Floating exception errors

[Triton]

Im writing a program in fortran 90/95, yes i know it is an obsolete language, and right now i am having a problem with some floatin exception errors. My assignment is to compare several recursive and non-recursive sorting algorithms and the time it takes them to sort a 3 or 20 thousand random real number array....the program compiles fine, but once i select which sort algorithm to use, i get a "floating exception" error and the program crashes.... maybe my problem is i dont know exactly what a floating exception error is, and i guess knowing exactly what it is would help alot, thanks

I'm pretty sure it's an arithmatic error. Check your code and make sure there is no place where you attempt to, or can attempt to divide a number by 0. Thats the most common arithmatic error you can look for.

Ive tried a few things, my program right now will sort an array with under 2 or 3 hundred pieces of data just fine no problem, but when i test it with a file containing 3 or 20 thousand pieces from the project specs thats when it messes up

Ahh i got it, it involved the way the length of a series of allocatable arrays was read
