Divide By Zero Exception In Java
divide by zero exception in Java without actually dividing by zero? up vote 18 down vote favorite 2 I have an I2C device that wants two inputs: a denominator and a numerator. Both are written to separate addresses, so no actual calculation (numerator/denominator) is done. The problem with this is that a divide by zero could occur on the I2C device, so a divide by zero divide by zero exception in java example error needs to be checked for. Ideally, exactly the same thing would happen if the dividing were done by the java code. At the moment, I've bodged an unused variable that does the division, but I'm worried it'll get optimized out: public void setKp(int numerator, int divisor) { int zeroCheck = numerator / divisor; //... doesn't use zeroCheck } Surely there's a better way! java exception math divide-by-zero share|improve this question asked Nov 1 '09 at 18:27 Eric 51k24114226 The answers suggesting checking divisor directly seem better, but I can't imagine this getting optimized away. Sure the zeroCheck might not get assigned, but the division has a potential to throw an exception, so I can't imagine it actually being optimized away. –Yishai Nov 1 '09 at 18:35 add a comment| 5 Answers 5 active oldest votes up vote 34 down vote accepted You should not throw an ArithmeticException. Since the error is in the supplied arguments, throw an IllegalArgumentException. As the documentation says: Thrown to indicate that a method has been passed an illegal or inappropriate argument. Which is exactly what is going on here. if (divisor == 0) { throw new
you have probably seen some. There are (at least) two distinguishable kinds of errors: syntax errors and exceptions. 8.1. Syntax Errors¶

It’s an annoyance if the recipient of your spreadsheet doesn’t know the tip and you spend more time defining the issue than it takes to fix it. Next https://www.timeatlas.com/excel-divide-by-0-error/ time, I’ll take the five minutes to fix my Excel formula so it doesn’t display http://www.java2s.com/Tutorial/Java/0080__Statement-Control/catchdividebyzeroerror.htm the #DIV/0! divide by zero error message.Dividing by Zero in ExcelWithout getting into a semantics debate, Excel does allow you to divide by zero. It also lets you know you have an error. In the resulting cell, it shows the famous line of #DIV/0!. It’s one of those error messages where the letters and numbers make sense, but you also wonder divide by if your PC is swearing at you.Although your PC isn’t mad, the message may fluster users. Some look at the alert and see the help text “The formula or function used is dividing by zero or empty cells” as shown below. Others might question the data integrity. Personally, I think it’s an aesthetic issue.The reason I got this Excel error was that I tried to divide my Cost value in C7 by my Catalog Count in D7. divide by zero This test ad cost $77.45 and generated 0 catalog requests. A similar error occurs if the Catalog Count cell was blank.Add Logic to Your Excel FormulaThere are several ways to fix this error. The best way would be to produce test ads that converted better, but you may not have control of this item. You do have control of Excel and an easy way to change this message is to use the IF function.This is a logic function where you can direct Excel to do one action if a condition is TRUE and another action if the condition is FALSE.In this case, I want Excel to take a different action if I have a Catalog Count of “0”. Otherwise, Excel can continue as normal.How to Display a Blank Value instead of #DIV/0!(For illustration purposes, these steps are using Excel 2007. The process is similar in other versions.)Create a column for your formula. (e.g. Column E Conv Cost) Click the next cell down in that column. (e.g. E2) Click Insert Function on the Excel ribbon. In the Insert Function dialog, select IF Click OK.In the Function Arguments dialog, click in the Logical_test field. Click the top cell in the column which you’re dividing by. (e.g. D2)In the same text field after the cell reference type =0.
