Questions tagged [divide-by-zero]

Division by zero is the division by any value that is exactly equal to 0 -- a computation with an undefined result.

In computing, a program error may result from an attempt to divide by zero. Depending on the programming environment and the type of number (e.g. floating point, integer) being divided by zero, it may generate positive or negative infinity by the IEEE 754 floating point standard, generate an exception, generate an error message, cause the program to terminate, or result in a special NaN (not a number) value.

Ignoring zero by division instances in script

Is there a way to ignore values in a list that create a division by zero in an iterative script instead of removing those problem values? I'm thinking along the lines of if if(x==0): break elif(x!=0): continue Where the values that aren't zero…

I was doing a code for , "Count Digits " , Evenly divides means whether N is divisible by a digit i.e. leaves a remainder 0 when divided

Why 1 / [(x ^ 2 - 1) ^ 0.5 - 1] returns a ZeroDivisionError when x > 10^9?

The exercise I was doing said that there'd likely be an issue when trying to solve this expression for 10^9 (first exercise is to try 10^7). I thought that it may have something to do with Python storing floats using 64 bits, but then the maximum…
