Keyword reference for floating-point

Question 97 (2004):

This is the error that came up when I tried to run my code:

    KROC: Floating-point error
    KROC: Fatal error code 42, core dumped
    Abort (core dumped)

Can you tell me what it means ?

Answer 97:

It means there was a floating point error.. If you've got access to the Linux (or cygwin) version of KRoC, compile with the "-d" flag (debugging) and it'll give you some useful information. Floating-point errors include: divide-by-zero, overflow, underflow, denormalised-operand and inexact-result. Chances are it's divide-by-zero (or modulo-by-zero).
