2進数を10進数に変換するC#プログラム

int num = 101;

binVal = num;

while (num > 0) { rem = num % 10; decVal = decVal + rem * baseVal; num = num / 10; baseVal = baseVal * 2; }

using System; using System.Collections.Generic; using System.Text; namespace Demo { class MyApplication { static void Main(string[] args) { int num, binVal, decVal = 0, baseVal = 1, rem; num = 101; binVal = num; while (num > 0) { rem = num % 10; decVal = decVal + rem * baseVal; num = num / 10 ; baseVal = baseVal * 2; } Console.Write("Binary Number: "+binVal); Console.Write("Decimal: "+decVal); Console.ReadLine(); } } }

Binary Number: 101 Decimal: 5
