Dec 2 hex.
if you wanted to convert a decimal number to a hexadecimal number, you can do it several ways. first you could do it the old fashion way by hand.
or you could use a C language program such as:
[code]
#include<stdio.h>
int main(){
long int decimalNumber,remainder,quotient;
int i=1,j,temp;
char hexadecimalNumber[100];
printf("Enter any decimal number: ");
scanf("%ld",&decimalNumber);
quotient = decimalNumber;
while(quotient!=0){
temp = quotient % 16;
//To convert integer into character
if( temp < 10)
temp =temp + 48;
else
temp = temp + 55;
hexadecimalNumber[i++]= temp;
quotient = quotient / 16;
}
printf("Equivalent hexadecimal value of decimal number %d: ",decimalNumber);
for(j = i -1 ;j> 0;j--)
printf("%c",hexadecimalNumber[j]);
printf("\n");
return 0;
}
[/code]
Compile it and then run it:
$ ./d2h
Enter any decimal number: 708
Equivalent hexadecimal value of decimal number 708: 2C4
or actually you could use either of two command line commands.
$ echo 'obase=16;ibase=10;708'| bc
2C4
or
$ printf '%x\n' 708
2c4
As you learn bash, you can see you can do things without getting real complicated.
