help with javascript please!

hi

i dont know if anyone can help me - but im stuck on a smal bit of programming and would appreciate some help.

i need to write a javascript function called difference ( ) that has the ability to take 2 numbers as arguments and return the difference between them, the number that the query returns always needs to be positive or 0, so the function needs to check for this as well

can anyone help?

see for the number to be always positive you have to just check whether the number is greater then zero or not and if it is greater then zero then you can display the number or else you can display zero in the answer.

a simple example is given below

var num1= 5
var num2 = 8
var result
result = num1 - num 2
var default 1 = 0;

if (result >0)
{
document.write(result );

}
else
{

document.write( default 1 );

}


I hope this will solve your problem.
