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

When we format any float value  that means we are changing its data type to string   So when we apply the formatting on any amount float value then it will set with all possible notations like dot  comma  etc  For example   float 0 00   gt   string  0 00    float 10000 56   gt   string   10 000 56   float 5000000 20  gt   string   5 000 000 20    So  logically it s not possible to keep the float datatype after formatting

As far as i know there is no solution for PHP to fix this  All other  above and below  answers given in this thread are nonsense   The number format function returns a string as result as written in PHP net s own specification    Functions like floatval doubleval do return integers if you give as value 3 00    If you do typejuggling then you will get an integer as result   If you use round   then you will get an integer as result   The only possible solution that i can think of is using your database for type conversion to float  MySQL for example   SELECT CAST  3 00  AS DECIMAL  AS realFloatValue    Execute this using an abstraction layer which returns floats instead of strings and there you go     JSON output modification  If you are looking for a solution to fix your JSON output to hold 2 decimals then you can probably use post-formatting like in the code below      PHP AJAX Controller     some code here     transform to json and then convert string to float with 2 decimals  output   array  x    gt   y    price    gt   0 00     json   json encode  output    json   str replace   price      output  price          price     output  price        json       output to browser   client print  json  exit      Returns to client browser     x   y   price  0 00
