decimal

问题 I already have a code which uses the bisection method to determine the value of something, the problem is that I need a value so precise, more than 15 decimals, and at some point python stops getting smaller digits I am aware of the Decimals library but do I really have to rewrite every parameter in the code as Decimals(parameter) ? because I have lots of parameters is there a way to convert every float in the code to Decimals universally? or is there a way to solve this problem all together

问题 Hi I want to find if there is any better way to parse the string to Decimal which covers various format $1.30 £1.50 €2,50 2,50 € 2.500,00 € I see a lot of examples using culture to convert . & , . But in my case, I don't have anything to identify the culture. This display field I get from the client and I need to extract the value. I tried following (which didn't work for all scenario) but would like to know if we have any best way to handle this. Decimal.Parse(value,NumberStyles.Currency |

问题 When I run this simple operation in SQL server: Select 800.0 /30.0 I get the value 26.666666, where even if it rounds for 6 digits it should be 26.666667. How can I get the calculation to be accurate? I tried to search about it online and I found a solution where I cast each operand to a high precision decimal before the operation, but this will not be convenient for me because I have many long complex calculations. think there must be a better solution. 回答1: When a using division, in SQL

问题 I have this sample code: let locale = Locale(identifier: "en_US") print("Language code: \(locale.languageCode ?? "nil")") print("Region code: \(locale.regionCode ?? "nil")") print("Decimal separator: \(locale.decimalSeparator ?? "nil")") Using en_US in this example (English as language and USA as region) makes the Locale’s decimal separator a . because this is the decimal separator in the specified region "USA": Language code: en Region code: US Decimal separator: . Using Locale(identifier:

问题 So I need to convert decimal to binary but all of my returns need to be 8 bits long. I've already figured out the conversion itself but I need to figure out how to add zero's to the beginning if it's less than 8 bits. old_number = int(input("Enter whole number here: ")) number = old_number binary_translation = 0 while number > -1: if number > 128 or number == 128: binary_translation = binary_translation + 10000000 number = number - 128 elif number > 64 or number == 64: binary_translation =

问题 In relation to: Convert Decimal to Double Now, I got to many questions relating to C#'s floating-point type called decimal and I've seen its differences with both float and double , which got me thinking if there is an equivalent to this type in C. In the question specified, I got an answer I want to convert to C: double trans = trackBar1.Value / 5000.0; double trans = trackBar1.Value / 5000d; Of course, the only change is the second line gone, but with the thing about the decimal type, I
