how to convert a float value to an integer number in php

Question

i have a function for forex site that subtract two numbers like the following example

140.50 - 140.00
1.1010 - 1.1050
1.5215 - 1.5058

what i get is the following

0.5

-0.004

0.0157

what i want to get is the following

50

-40

157

i have tried the following

$number = 1.5058 - 1.5215;
list($real, $decimal) = explode('.', $number);
echo $result = $number*pow(10,strlen($decimal));

but i got

5

-4

157

because the zero in the right is no sense for it

Answer 1

Is this what you are after ?

function remdec($num) { return intval(str_replace(".", "", strval($num))); }

$number = remdec(1.5058) - remdec(1.5215);
echo $number;
