PHP Numbers: Integer vs Float Explained
In PHP, “number” is not a specific data type or keyword. Typically, when we refer to “number” it can mean numerical data types such as integers or floating-point numbers. In PHP, numbers can be represented as integers or floats.
- An integer is a number that does not have a decimal part and can be a positive number, negative number, or zero.
- Float: a floating-point number is a number with a decimal part, also known as a double precision number.
When dealing with numerical values, PHP will automatically recognize whether it is an integer or a float based on the context, without the need to explicitly specify the data type.
