How do youmake a decimal a whole number?

[username746]

I am currently writing an algorithm for searching a text file.(i believe this is called binary searching.)

I am taking the beinning row number (B_row) minus the last row number (L_row)= compaire number (C_num)

then divide by two and see where the value i am searching lies. if it is in the top part, set C_num as L_row and keep going till it finds it. mathmaticallic the actual searching is much much less than a fread.

anyway, my question is: when i get a decimal like this
--> compaire - 32768.5
high - 65536
low - 1

i want to make it a whole number. (like 32768)

i have searched and read, and cannot seem o find a function suited for this. i found
--> settype($C_num, "integer");

anyone have a helpful suggestion?

Keep in your mind.The PHP is maden by Programmers for the Programmers.
I don't found a problem (yet) that can be solved using PHP.
