A little help with my script would we appreciated.

[Tasemu]

Hey im making a script that calculates compound interest and everything should be working fine but when i run the script the answer is incorrect, i know the math is not wrong. Possibly the $I is automatically rounding off to a whole number (it is usually a decimal).

Anyway any help or tips would be appreciated.

Code:

<?php
/* This is the amount of money.
$P = $_POST["element_1"];
/* This is the % of interest (e.g. 18% is 0.18).
$I = $_POST["element_2"];
/* This is the time range.
$T = $_POST["element_3"];
/* This is to tell of any rests (e.g. monthly = 12, weekly = 52 and none = 1)
$K = $_POST["element_4"];
/* This is for the function below, its just T times K.
$N = $T*$K;

/* Heres the main function to find the compound interest.
$A = $P*(1+($I/$K))^$N;

print "Compound Interest is $A";
?>

Peace,

iPhish.
