Description

public BcMath\Number::__construct(stringint $num)

Creates a BcMath\Number object from an int or string value.

num
An int or string value. If num is a int, the BcMath\Number::scale is always set to 0. If num is a string, it must be a valid number, and the BcMath\Number::scale is automatically set by parsing the string.

Examples

Example #1 BcMath\Number::__construct example

<?php
$num1 = new BcMath\Number(100);
$num2 = new BcMath\Number('-200');
$num3 = new BcMath\Number('300.00');

var_dump($num1, $num2, $num3);
?>

The above example will output:

object(BcMath\Number)#1 (2) {
  ["value"]=>
  string(3) "100"
  ["scale"]=>
  int(0)
}
object(BcMath\Number)#2 (2) {
  ["value"]=>
  string(4) "-200"
  ["scale"]=>
  int(0)
}
object(BcMath\Number)#3 (2) {
  ["value"]=>
  string(6) "300.00"
  ["scale"]=>
  int(2)
}
