function split_number ( $number ) 
{
    //Convert any entered number into a float
    $number = number_format ( $number, 1 );

    //Get the integer part
    $intpart = floor ( $number );

    //Get the fraction part
    $fraction = $number - $intpart;
}

I needed to split a decimal number into the integer part and the fraction part and save both of them in different variables
