PHP String to Float

Question

I am not familiar with PHP at all and had a quick question.

I have 2 variables pricePerUnit and InvoicedUnits. Here\'s the code that is set

Answer 1

Dealing with markup in floats is a non trivial task. In the English/American notation you format one thousand plus 46*10-2:

1,000.46

But in Germany you would change comma and point:

1.000,46

This makes it really hard guessing the right number in multi-language applications.
I strongly suggest using Zend_Measure of the Zend Framework for this task. This component will parse the string to a float by the users language.
