Decimal to hexadecimal conversion using CAPL - capl

Question

Is there any CAPL function for converting decimal value into hexadecimal value? I have already looked in help option of CAPL browser.

Answer 1

Assuming that you want the number to be converted to a string, that you can print out. Either to the write window, into the testreport, etc.
You can use snprintf like this:
snprintf(buffer,elcount(buffer),"%x",integervariable);
where buffer is a char array big enough.
This example is taken from the Vector knowledge base and was among the first result on google.

Answer 2

For hexadecimal equivalent value:
You can make use of _pow function (returns x to the power of y) and while in the following way, which would return you the hexadecimal equivalent value:
double decToHexEquivalent(int n)
{
int counter,remainder,decimal_number,hexadecimal_number = 0;
while(n!=0)
{
remainder = decimal_number % 16;
hexadecimal_number = hexadecimal_number + remainder * _pow(10, counter);
n=n/16;
++counter;
}
return hexadecimal_number;
}
you can call the above function in the following way:
testfunction xyz(int n)
{
write("Hexadecimal:%d", decToHexa(n));
}
Caution: not tested
For hexadecimal value
declare a global variable char buffer[100] in the variable section
variables
{
char buffer[100];
}
and then using snprintf function you can convert an integer variable to a character array, like this:
void dectohexValue(int decimal_number)
{
snprintf(buffer,elcount(buffer),"%02X",decimal_number);
}
then finally you can use the function as follows:
testfunction xyz(int n)
{
dectohexValue(n);
write("Hexadecimal:%s", buffer);
}
