Buffon![]() |
Estimate the value of p using Buffon's "needles." Use a Monte Carlo method for estimating the numeric value of p by randomly throwing short line segments (e.g., needles, toothpicks, pencils, etc.) onto a plane of equally-spaced parallel lines (e.g., brick sidewalks, hardwood floors, certain tiles, table cloth, etc.). The number of segments crossing the parallel lines is related to the value p. Count Buffon first experimented with this method in the 1700s. | pi, Monte Carlo method, Count Buffon, Random, Plural, TBitmap, TImage, Pixels, MoveTo, LineTo, FillRect, TextOut, TSimplePantograph, ShellExecute, Application.ProcessMessages, Cancel button, FormatFloat, ArcTan2, RGB, MessageBeep(MB_ICONEXCLAMATION), Procedure variable, Half-Angle Formula, Rotation Matrix |

| CRC |
CRC Calculator: CRC-16 and CRC-32 calculations. CRC16Dem and CRC32Dem are examples of command-line programs that work in Delphi 1, 2 or 3 (updated 3/20/98). The CRCCalculator interactively shows CRC-16 or CRC-32 for a given string. | cyclic redundancy check, CRC-16, CRC-32, APPTYPE CONSOLE, CRC calculator |
