  • How can I find coordinate of a location in Delphi

    To find the coordinates (latitude and longitude) of a location in Delphi, you can use a geocoding service that converts a physical address or place name into geographic coordinates. One way to do this is to use the Google Maps Geocoding API, which allows you to programmatically retrieve the latitude and longitude for a given…

  • How can I calculate distance between to coordinates in Delphi

    To calculate the distance between two coordinates (points) in Delphi, you can use the Haversine formula, which is a method used to calculate the great-circle distance between two points on a sphere based on their longitudes and latitudes. Here is a function that you can use to calculate the distance between two coordinates in Delphi:…

  • Solving pool problems in delphi

    Here is a function in Delphi that you can use to solve pool problems: function SolvePoolProblem(volume: Double; length: Double; width: Double; depth: Double): Double; var surfaceArea: Double; begin // Calculate the surface area of the pool surfaceArea := length * width + (length * depth * 2) + (width * depth * 2); // Calculate…

  • Calculating distance of two planets in delphi

    To create a function for calculating the distance between two planets in Delphi, you will need to consider a few different factors: You will need to know the positions of the two planets in 3D space. This can be represented by their coordinates (x, y, and z) in some reference frame. You will need to…

  • Calculating population in delphi

    To create a function for calculating the population of a given area in Delphi, you will need to consider a few different factors: You will need to know the size of the area in some unit of measurement, such as square kilometers or square miles. You will need to know the population density of the…

  • How can I use randomize, random and randomrange in Delphi

    In Delphi, you can use the Randomize function to initialize the random number generator, the Random function to generate a random floating-point value between 0 and 1, and the RandomRange function to generate a random integer within a given range. Here’s an example of how to use these functions uses System.SysUtils; var R: Real; I:…

  • How can I use math functions in Delphi

    Delphi includes a number of math functions in its standard library, which you can use by including the Math unit in your program and calling the functions as needed. For example uses Math; var x, y: Double; begin x := Cos(0.5); y := Exp(2.7); end; Here are some of the math functions that are available…

  • Creating random passwords with given lenght in Delphi

    To create a function for generating random passwords in Delphi, you can use the following steps: Start by creating a function that takes an integer parameter for the password length. This will allow you to specify the length of the password when you call the function. Initialize a string variable to store the password as…

  • Calculating distance of two strings in delphi

    To create a function for calculating the distance between two strings in Delphi, you can use the Levenshtein distance algorithm. This is a measure of the difference between two strings, where the distance is the minimum number of single-character edits (insertions, deletions, or substitutions) required to transform one string into the other. Here is an…

  • How can I convert mm to inch in delphi

    To convert millimeters to inches in Delphi, you can use the following formula: inches = millimeters / 25.4 Here is an example of how you can use this formula in a Delphi function: function MillimetersToInches(millimeters: Double): Double; begin Result := millimeters / 25.4; end; You can then call this function with a value in millimeters,…
