Question

I'm having difficulties understanding the below code. What does this mean?

if((($weight-0.5)%2)>0 && (($weight-0.5)%2)/2 < 0.25) {      
    $price=$initial+(($weight-0.5)/2)*$lessthan15kg;    
}  

Answer 1

This in your if statment mean ($weight-0.5)%2)>0 --This mean if the remainder is greater than zero

($weight-0.5)%2)/2 < 0.25 -- This means if you devide remainder by Two and its less than 0.25.

in the middle you got && in your if statement. Thats mean both the condition has to be true(IN other words both condition should be met). than your code will get executed
