Let fabs be a function that returns the absolute value of a float. Then the formula could look like this: function calcRank(float v1, float v2) { float k = fabs(v2-30.0); if (k < 30.0) { // Rule 1 and 2 rank = k/60.0 + (60.0-k) * v1 / 60.0; } else { // Rule 3 … Read more
There are 52 weeks in a year, so weeklySalary = yearlySalary / 52. If you want hourly, there are 40 working hours in a week, so hourlySalary = weeklySalary / 40. 0 solved Converting Yearly Salary to Weekly in Swift
This is a math question, not programming, but you ask for javascript here you are an example: var value = 249; var total = 1000; var calcPercent = function(v, t) { return 100*v/t; }; alert(calcPercent(value, total)+”%”); solved Get the percentage of a number with javascript [closed]
let hr = date.getHours(); let min = date.getMinutes(); let sec = date.getSeconds(); let hrPosition = hr*360/12 + ((min * 360/60)/12) ; let minPosition = (min * 360/60) + (sec* 360/60)/60; let secPosition = sec * 360/60; hrPosition -> full circle has 360 degrees, on clock it’s 12 hours, so 1 hour is 360/12 = 30 … Read more
I tried to reproduce the error. The error I got is: TypeError: must be real number, not list If the error is same then it was solved by doing this: thisJ = temp7 * math.exp(temp6[0][0]) Because temp6 type is list containing list containing array object. Please do correct me if I am wrong. 0 solved … Read more
Q: How do I fix problem 1 … ? 10 ^ i is 10 exclusive-or’ed with i. It is not 10i. To find the integer portion of log10(num) int i_portion = 0; if (num <= 0) Handle_elsewhere(); else { int i_portion = 0; int n = num; while (n >= 10) { n /= 10; … Read more
I found the shortest way to do this using Math.NET Symbolics from Math.NET The key syntax to do so is like this: SymbolicExpression.Parse(“a*(b+c)”).Expand().Summands().Select(x => x.Factors()); In it, I expand the expression and then I get the summands. For each of the summands, I get the factors. To illustrate it better, consider the following expression: a … Read more
Integers don’t have fractions. Use decimal if you want reliable numeric values with decimals. decimal box1 = decimal.Parse(Number1TextBox.Text); decimal box2 = decimal.Parse(Number2TextBox.Text); decimal box3 = decimal.Parse(Number3TextBox.Text); decimal answer = box1 * box2 * box3; You can round back the result like this: decimal rounded = Math.Round(answer); 5 solved C# basic Math, want to use decimals … Read more
First, you need to rethink how to reverse a number. Basically, what you want to do is to have a running total starting from 0. Then starting from the rightmost digit in the number to reverse, you 1) Take the total and multiply it by 10. This “moves” the digits of the running total to … Read more
First of all, you always must include the description of what you have tried so far and what error you encountered while doing so. It is not nice to ask a question directly without showing your efforts in it. Now coming back to your question, it is actually quite very easy, what you can do … Read more
Building on what @Aditi Rawat said, I’ve wrote a little program that does what you need using the quadratic roots formula. Not sure if you need to do it that way or not but this solves the problem: #include <iostream> #include <cmath> using namespace std; int main() { double a, b, c; cout<<“Enter a: “; … Read more
The / operator looks at its operands and when it discovers that they are two integers it returns an integer. If you want to get back a double value then you need to cast one of the two integers to a double double difference = (endX – startX + 1) / (double)ordinates; You can find … Read more

Assuming $arr is your initial array, and $new_arr will be the new one. $new_arr = array(); foreach ($arr as $i=>$ar) foreach ($ar as $j=>$a) $new_arr[$i][$j] = round(($a/array_sum($ar))*100, 1); solved Sum up values in multidimensional php array [closed]
Express that the center of the sphere is equidistant to the three given points and coplanar with them (assuming that the three given points are on a great circle). (X – Xa)² + (Y – Ya)² + (Z – Za)² = R² (X – Xb)² + (Y – Yb)² + (Z – Zb)² = R² … Read more
