I connect to a MongoDB with the latest C-Driver. When I insert a float value, say 1.0043820142745972, and then query it back I only seem to get 1.004382!
Hi IVgot the the cpp file where i Initialize.
Hi
I am executing below command to do summation on 46th coloumn.
Code:
cat File1| awk -F"|" '{p += $46} END { printf"Column Name | SUM | " p}'
I am getting output as
Code:
Column Name | SUM | 1.01139e+10
Here I want output in Proper decimal format. Can someone tell me what change is required for same?
Hey again,
I have a basic regex that tests if a number is a float.
Code:
validFloat='^[-|0-9|.][.0-9]*$'
The aboveworks pretty well, but it allows for multiple decimal points.
Android Sensor Listener is reading accelerometer data in float with up to 6 or 7 decimal points.I don't need that kind of accuracy.Is there a way to read just till 1 or 2 decimal points and decrease the overhead.
I'm still a bit of a noob regarding this. I'm puzzled about what's happening. I stored a 3.542 in a sqlite database. Checking the database with Firefox sqlite viewer confirmed this.
I have searched and the answers I have found thus far have led me to this point, so I feel I am just about there.
I am trying to convert a column of hexadecimal to decimal values so that I can filter out via grep just the data I want. I was able to pull my original 3 character hex value and append 0x to the front but the printf statement seems not to work to convert it to decimal.
I am taking a look at large matrix multiplication and ran the following experiment to form a baseline test:
Randomly generate two 4096x4096 matrixes X, Y from std normal (0 mean, 1 stddev).
Z = X*Y
Sum elements of Z (to make sure they are accessed) and output.
Here is the nieve C++ implementatation:
#include <iostream>
#include <algorithm>
using namespace std;
int main()

I'm trying to add a hue to a color but I don't know why there is error on methods
public Color getHueColor(float hue){
Color c = new Color();
hue = (float) (hue * 0.0027777777);
// Get saturation and brightness.
int r = 247;
int g = 121;
int b = 121;
float[] hsv = new float[3];
Color.RGBtoHSB(r,g,b,hsv);
// Pass .5 (= 180) as HUE
c = Color.HSBtoRGB(hue,
