double

问题 Just a day before I participated in the qualification round of Google Code Jam. This is my first experience of such an online coding contest. It was really fun. There were three problems given of which i was able to solve two. But on one of the problems I was asked to work with values that are really huge. I am a Java guy and I thought I would go for double variable. Unfortunately, the precision of double also was not enough. Moreover, I attended this during the closing stage, I was not

问题 let's say I have following SQL column: Now, I want to do following: In col_1, I have the value 'one'. If I check, which corresponding values I get in col_2 I get for that, I find 'two' and 'three'. So the results would be 'two' and 'three'. But from this result set, I want to only have those, that, used in col_1 , have, in col_2, the corresponding value 'one'. So: 'two', in col_1 , does have 'one' in col_2 , but three doesn't. So, from the result set of {'two', 'three'} only {'two'} would

问题 I have a cuda loop where a variable cumul store an accumulation in double : double cumulative_value = (double)0; loop(...) { // ... double valueY = computeValueY(); // ... cumulative_value += valueY } This code is compiled on different SDK and run on two computers : M1 : TeslaM2075 CUDA 5.0 M2 : TeslaM2075 CUDA 7.5 At step 10, results are differents. Values for this addition (double precision representation in hexadecimal) are: 0x 41 0d d3 17 34 79 27 4d => cumulative_value + 0x 40 b6 60 1d

问题 Below I attempt to assign to value the maximum Long value, then add to it the minimum positive Double value possible. I then try to detect that the value is greater than the maximum Long value. Double value = new Long(Long.MAX_VALUE).doubleValue(); value += Double.MIN_VALUE; if (value < -(new Long(Long.MAX_VALUE).doubleValue()) || value > new Long(Long.MAX_VALUE).doubleValue()) { // Expecting code here to execute, but it doesn't. } Studying the values involved shows that value has the final

问题 Using JSONObject to read a json response from a server. The server returns some decimal number. Normal numbers are not a problem to but the problem occurs when there is decimal number of form 0.00068 . Numbers like 0.00068 are automatically stored into Double object and when an attempt is made to retrieve such number returns "computerized scientific notation" of the number , that is 6.8E4 even if the number accessed as double by getDouble(index) method or as String with getString(index)

问题 This question already has answers here : How do I print a double value with full precision using cout? (10 answers) Closed 5 years ago . I'm trying to convert a string into a double but my double gets cut off at the 3rd decimal point. My string looks like this: "-122.39381636393" After it gets converted it looks like this: -122.394 void setLongitude(string longitude){ this->longitude = (double)atof(longitude.c_str()); cout << "got longitude: " << longitude << endl; cout << "setting longitude:
