4.2352941176470588235294117647 contains 29 digits. decimal is define to have 28-29 significant digits. You can’t store a more accurate number in a decimal. What field of engineering or science are you working in where the 30th and more digits are significant to the accuracy of the overall calculation? (It would also, possibly, help if you’d shown … Read more
MathWorld had a great heart shaped function; http://mathworld.wolfram.com/HeartCurve.html Basically you have to do something like this in your code; float fraction = (float) this.currentStep / (float) this.steps; –> float t = this.currentStep * 2.0 * Math.PI / (float) this.steps; this.x = 16.0 * Math.pow(Math.sin(t), 3.0)); this.y = 13.0 * Math.cos(t) – 5.0 * Math.cos(2.0 * … Read more

You can write n-linear equations as one matrix equation to solve it. Here you can find great example: http://blogs.mathworks.com/pick/2007/09/13/matlab-basics-video-solving-linear-equations/ (video!)

Numerical derivation and integration in code for physics, mapping, robotics, gaming, dead-reckoning, and controls Pay attention to where I use the words “estimate” vs “measurement” below. The difference is important. Measurements are direct readings from a sensor. Ex: a GPS measures position (meters) directly, and a speedometer measures speed (m/s) directly. Estimates are calculated projections … Read more
Here is a regex that should work. Note that I made a change in your LaTeX expression because I think there was an error (* sign). astr=”\frac{(\ChebyU{\ell}@{x})^2}{\frac{\pi}{2}}” import re pat = re.compile(‘\\frac\{(.*?)\}\{\\frac\{(.*?)\}\{(.*?)\}\}’) match = pat.match(astr) if match: expr=”\\frac{{{0}*{2}}}{{{1}}}”.format(*match.groups()) print expr NB: I did not include the spaces in your original expression. 0 solved Using Python … Read more
The operator precedence of C++ is the standard mathematical precedence, where % has the same precedence as /. So, the expression m = 605 / 10 + 45 % 7 + 29 % 11; would be evaluated as m = (605 / 10) + (45 % 7) + (29 % 11); Which would result in: … Read more
You can loop over values like this: for x in [-60.0, -45.0, -30.0]: # etc; notice how the .0 specifies a float print(‘D({0}) = {1}’.format(x, A*math.cos(x)**2+B*math.sin(x)+C)) If you intend for the output to be machine-readable, maybe change the format string to something like ‘{0},{1}’ for simple CSV output. Just print will print nothing (well, or … Read more
In the 2×2 case you have 6 possible ways you say. (So I infer from that that you actually move from grid-point to grid-point rather than from cell to cell): (r,r,d,d), (r,d,r,d), (r,d,d,r), (d,r,d,r), (d,d,r,r), (d,r,r,d). Note that we always have 2 ‘d’s and 2 ‘r’s. And we always have 4 moves (_ , _, … Read more
I hope you will still edit your question with some more criteria and what you have tried so far, however, following implementation follows: No 0 numbers ; The resulting array should be exactly the requested numbers long ; It doesn’t check if the division is possible, theoretically, the targetNumber – totalSumNumbers >= 0 has to … Read more
I don’t understand why you are using std::vector. You could calculate the sum without using the vector: int k=0,sum=0; for(int i=0;i<s.length();i++) { k = s[i]-‘0′; sum += k; } Note: if you are a little paranoid of the sum value fitting into an integer, you can use an unsigned integer since digits can’t be negative. … Read more
The result is correct. Try to visualize it: Distance between -110 and 100 is the sum of distance between -110 and 0 (Mathf.Abs(-110 – 0) = 110) and distance between 100 and 0 (Mathf.Abs(100 – 0) = 100). That is: 110 + 100 = 210. Perhaps you have a different operation in mind? If you … Read more
It looks like you are saving the Unix Timestamp to your file, you can try and make it human readable using an online time converter (https://time.is/Unix_time_converter) Besides this, take some time to read the os.time() implementation details on this lua page: https://www.lua.org/pil/22.1.html The time function, when called without arguments, returns the current date and time, … Read more
Numbers prefixed with 0 are treated as octal numbers: $x = 012;//$x is 10 Details here The reason that $x = ‘012’; works is because PHP converts that to an integer without treating it as an octal number. 0 solved Number with 0 on the front? [closed]
