divide-by-zero

I have a situation where it is reasonable to have a division by 0.0 or by -0.0 where I would expect to see +Inf and -Inf, respectively, as results. It seems that Python enjoys throwing a ZeroDivisionError: float division by zero in either case. Obviously, I figured that I could simply wrap this with a test for 0.0. However, I can't find a way to distinguish between +0.0 and -0.0. (FYI you can easily get a -0.0 by typing it or via common calculations such as -1.0 * 0.0). IEEE handles this all very nicely, but Python seems to take pains to hide the well thought out IEEE behavior. In fact, the

ads = ads.Where(x => (x.Amount - x.Price) / (x.Amount / 100) >= filter.Persent); if x.Amount == 0 I have error "Divide by zero error encountered." like me in this request is to avoid? update: this helped, but I do not like the decision: ads = ads.Where(x => (x.Amount - x.Price) / ((x.Amount / 100)==0?0.1:(x.Amount / 100)) >= filter.Persent); there is another way? ads = ads.Where(x => x.Amount != 0 && (x.Amount - x.Price) / (x.Amount / 100) >= filter.Persent); Of course, you can always implement a generic safe division method and use it all the way using System; namespace Stackoverflow { static

How to handle the divide by zero exception in List Comprehensions while dividing 2 lists in Python: From below example: from operator import truediv result_list = map(truediv, [i for i in list1], [j for j in list2]) where the list2 can contain the 0 as value. I want to handle the exception in the same line due to my code constrain. Please help me. You cannot . try is a (compound) statement , a list-comprehension is an expression . In Python these are completely distinct things and you cannot have a statement inside an expression. The thing you can do is using a wrapper function: def add

Customer reported an error in one of our programs caused by division by zero. We have only this VLM line: kernel: myprog[16122] trap divide error rip:79dd99 rsp:2b6d2ea40450 error:0 I do not believe there is core file for that. I searched through the Internet to find how I can tell the line of the program that caused this division by zero, but so far I am failing. I understand that 16122 is pid of the program, so that will not help me. I suspect that rsp:2b6d2ea40450 has something to do with the address of the line that caused the error (0x2b6d2ea40450) but is that true? If it is then how can

We are having a problem with the KeyManagerFactory in the Sun JRE 1.6. We are using code similar to the following to upload and use a certificate in p12 format: KeyStore keyStore = KeyStore.getInstance(PKCS12); KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(SUN_X509); InputStream certificateFile = getSSLCertificate(); String certificatePassword = getSSLCertificatePassword(); keyStore.load(certificateFile, certificatePassword); keyManagerFactory.init(keyStore, certificatePassword); This code works correctly when the certificate password exists. But when the certificate
