b=300000000000000000000^m
c=40000000000000000000^m
d=250000000000000^m

e=$( awk -v var1=$a var2=$b var3=$c var4=$d 'BEGIN{print var1 * var2 / var3 + var4}' )

But this example above didn't work. Do you have any suggestion for this?
I didn't see calculation part -v is missing
Code:
e=$( awk -v var1=$a -v var2=$b -v var3=$c  -v var4=$d 'BEGIN{print var1 * var2 / var3 + var4}' )

+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.0.3 | | | | | | | get_class_vars(3) will only return the properties | | | that can be accessed from the current scope. | | | | | 5.0.2 | | | | | | | Calling get_class_vars(3) will now expose all | | | the properties as an array, unlike previous be- | | | haviour where protected and private properties | | | were prefixed with nul bytes. | | | | | 5.0.1 | | | | | | | Calling get_class_vars(3) will expose all prop- | | | erties, as when converting an object to a class. | | | | +--------+---------------------------------------------------+ EXAMPLES
Example #1 get_class_vars(3) example <?php class myclass { var $var1; // this has no default value... var $var2 = "xyz"; var $var3 = 100; private $var4; // constructor function myclass() { // change some properties $this->var1 = "foo"; $this->var2 = "bar"; return true; } } $my_class = new myclass(); $class_vars = get_class_vars(get_class($my_class)); foreach ($class_vars as $name => $value) { echo "$name : $value "; } ?> The above example will output: var1 : var2 : xyz var3 : 100 Example #2 get_class_vars(3) and scoping behaviour <?php function format($array) { return implode('|', array_keys($array)) . " "; } class TestCase { public $a = 1; protected $b = 2; private $c = 3; public static function expose() { echo format(get_class_vars(__CLASS__)); } } TestCase::expose(); echo format(get_class_vars('TestCase')); ?> The above example will output: // 5.0.0 a| * b| TestCase c a| * b| TestCase c // 5.0.1 - 5.0.2 a|b|c a|b|c // 5.0.3 + a|b|c a SEE ALSO
