PHP公式需要计算一个简单的格式

Question

I am trying to take an amount and convert it to a units type format...

For example:

( note: don't worry about the dollar sign )

Total is $400

I need to display it as 4 * 100

Another Example

Total is $450

I need to display it as 4 * 100 | 50 * 1

So another words there are only 100 and 1 units.

I was thinking for 3 hours already and nothing seems to come to mind...Perhaps someone out there has done something similar and already know the answer?

Answer 1

Hoping I am not doing your homework. Try this:

$num = 450;
$ones = $num % 100;
$hundreds = floor($num / 100);
echo "$hundreds * 100 | $ones * 1";
