Just contact the assembly, a lot of details are not very clear, wrote a decimal and hexadecimal conversion between the program (a bit of a setback.) ) as a practiced hand.Post code, hope that the passing of Daniel can give some guidance.Idea: (10->16) decimal number input when single character processing, meet enter end input, finally get a

Conversion between binary, octal, decimal, and hexadecimal 1. [binary (0 ~ 1), octal (0 ~ 7), decimal (0 ~ 9)] → hexadecimal (0 ~ ~ 15→a ~ F) 101011 → 1*20 + 1*21 + 0*22 + 1*23 + 0*24 + 1*25 = 1 + 2 + 0 + 8 + 0 + 32 = 43 053 → 3*80 + 5*81 = 3 + 40 = 43 0x2B = B * 160 + 2*161 = 11 + 32 = 43 2.

Convert any decimal places into 2, 3, 4, 5, 6, 7, 8, and 9 decimal places, retain 8 digits after the decimal point, and output. For example, if the decimal point is 0.795, the output is: Decimal

//decimal into binaryConsole.WriteLine (Convert.ToString (69, 2));Decimal Turn octalConsole.WriteLine (Convert.ToString (69, 8));Decimal Turn hexConsole.WriteLine (Convert.ToString (69, 16));//binary Turn decimalConsole.WriteLine (Convert.ToInt32 ("100111101″, 2)");Octal goto DecimalConsole.WriteLine (Convert.ToInt32 ("76″, 8)");

Taking into account the opposite, here the complete code, by the way, can be considered to implement R hexadecimal and decimal conversion. Complete code: 1 # include The algorithm is quite simple and easy to understand. for example, in hexadecimal 3c, the numbers are sequentially obtained from right to left. The size of the binary value of C is 12 through (and)

The problem description enters a positive hexadecimal number string that does not exceed 8 bits from the keyboard, converting it to a positive decimal number after the output.Note: 10~15 in hexadecimal numbers are denoted by uppercase letters A, B, C, D, E, F, respectively. Sample input FFFF sample output 65535 ideas: Feel yourself the following two methods are r

Var a = '20140901 ';Alert (parseInt (a, 2); // convert 111 as a binary value. Ignore 60 (not binary) and convert from left to right only binary values.Alert (parseInt (a, 16); // convert allAccording to this method, it can be converted to any hexadecimalVar a = '20140901 ';Alert (parseInt (a, 10). toString (16); // convert
