27 sie 2009 · string prd(const double x, const int decDigits) { stringstream ss; ss << fixed; ss.precision(decDigits); // set # places after decimal ss << x; return ss.str(); } You can then output any double myDouble with n places after the decimal point with code such as this: std::cout << prd(myDouble,n);
With the distance calculator distance.to you can easily determine distances between world-wide locations. Simply enter any desired location into the search function and you will get the shortest distance (air line) between the points, the route (route planner) as well as all important information.
2 cze 2017 · To print 4 digits after dot, we can use 0.4f in printf (). Below is program to demonstrate the same. // C program to set precision in floating point numbers. // using format specifier. #include<stdio.h>. int main() . {. float num = 5.48958123; // 4 digits after the decimal point .
7 lut 2017 · I'm trying to create a function that allows me to get the distance between the object and another point. I'm have trouble with it though any help would be brilliant. Point(void); Point(double anX, double aY); ~Point(); void setPoint(double anX, double aY); double getX(); double getY(); double scaleX(double theX);
This calculator will find the straight-line (great circle) distance between two locations of any kind: street addresses, city names, ZIP codes, etc. (The coordinates of the locations are provided by the Google Geocoding API.)
You can calculate the length of a path, running route, fence, border, or the perimeter of any object that appears on a google map. The distance calculator will then display a measurement of the length in feet, meters, miles and kilometers.
Free calculators to compute the distance between two coordinates on a 2D plane or 3D space. Distance calculators for two points on a map are also provided.
