Converting Hexadecimal to Decimal

If you are unfamiliar with hexadecimal numbers please look here:
http://www.permadi.com/tutorial/numHexToDec/

I looked around and didn't find a hexadecimal to decimal conversion function
and I needed one for one of my projects so I wrote one.

Code:

public HexToDec(value[])

{

        new string[32];

        copy(string,sizeof(string)-1,value);

        strtoupper(string);

        new temp = 0;

        new len = strlen(string);

        new i = len;

        while( i > 0 )

        {

                new dec = 0;

                switch( string[i-1] )

                {

                        case 'A': dec = 10;

                        case 'B': dec = 11;

                        case 'C': dec = 12;

                        case 'D': dec = 13;

                        case 'E': dec = 14;

                        case 'F': dec = 15;

                        case '0': dec = 0;

                        case '1': dec = 1;

                        case '2': dec = 2;

                        case '3': dec = 3;

                        case '4': dec = 4;

                        case '5': dec = 5;

                        case '6': dec = 6;

                        case '7': dec = 7;

                        case '8': dec = 8;

                        case '9': dec = 9;

                }

                temp += dec*power(16,(len-i));

                i--;

        }

        return temp;        

}

My dayz This is awesome, dude this helped me alot .... really, not just to make u proud, I used this for some stuff like map originz an all :D!
+k!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Re: Converting Hexadecimal to Decimal

Code:

public HexToDec(hex[])

{

    new i, result, value

    while((value = isxdigit(hex[i++])) != -1)

    {

        result = result * 16 + value

    }

    return result

}

 

isxdigit(ch)

{

    if(!ch)

        return -1

    

    if('0' <= ch <= '9')

        return ch - '0'

    

    ch &= ~0x20

    if('A' <= ch <= 'F')

        return ch - 'A' + 10

    

    return -1

}

try this
