[SOLVED] calculations

[mmarif4u]

Hi,

i need some help in a calculation script.

I am getting data from a sms, which i explode further.

In every sms 9 values are coming,till to explode part everything is fine.

Now i want to calculate that values.

some thing like:

<?php
$x="1,2,3,4,4,5,6,7,8,9";
list($ch1_1,$ch2_1,$ch3_1,$ch1_2,$ch2_2,$ch3_2,$ch1_3,$ch2_3,$ch3_3) = explode(",",$x);
echo $ch1_3."<br>";
echo $ch3_2;
?>

 

Now i want to to do further calculations like:

$ch1_1=a0+(a1*$ch1_1¹)+(a2*$ch1_1²)+(a3*$ch1_1³)+(a4*$ch1_1⁴)..........;

 

a0 and ...... are coming from table, it is also ok.

 

Now how can i calculate:

$ch1_1¹ and then $ch1_1²

mean something like square root and cube root and so on...

use this:

<?php

var_dump(pow(2, ); // int(256)
echo pow(-1, 20); // 1
echo pow(0, 0); // 1

echo pow(-1, 5.5); // PHP >4.0.6  NAN
echo pow(-1, 5.5); // PHP <=4.0.6 1.#IND
?>
