use: define("GREETING", "Hello you.", true); 1st parameter is the name for your constant 2nd parameter is the value of that constant 3rd parameter is whether or not you want the constant to be case-insensitive. Default is case sensitive. http://php.net/manual/en/function.define.php
most of the time you will get that written on a broadcast on BBM if this is the case, it stands for 'very sorry for the broad-cast'..
Generally, constant names are case sensitive in PHP.But... you can do a trick. If you will be consistent and all constant name will be defines as uppercase, you can access them using a combination of constant() and strtoupper() functions. Look at this example:?phpdefine(MY_CONSTANT, "HELLO");echo constant(strtoupper(my_constant));echo "";echo constant(strtoupper(My_Constant));echo "";echo constant(strtoupper(my_CONSTANT));?>
4.705 is a decimal value. So I presume you mean what is it when rounded to two decimal places. In that case 4.71 is the answer.
if you mean ratio? lets say its 1 to 5 make the denominator 100 (in this case by multiplying top and bottom by 20) the top number will be the percent (in this case: 1 x 20 = 20 therefore 20%)
