PHP float with 2 decimal places: .00

Question

When I do this typecasting:

(float) \'0.00\';

I get 0. How do I get 0.00 and still have the data type as a float?

Answer 1

A float isn't have 0 or 0.00 : those are different string representations of the internal (IEEE754) binary format but the float is the same.

If you want to express your float as "0.00", you need to format it in a string, using number_format :

$numberAsString = number_format($numberAsFloat, 2);
