PHP: Tips of the Day

Float

Example:

$float = 0.123;

For historical reasons "double" is returned by gettype() in case of a float, and not simply "float"

Floats are floating point numbers, which allow more output precision than plain integers.

Floats and integers can be used together due to PHP's loose casting of variable types:

$sum = 3 + 0.14;
echo $sum;

Output:

3.14

php does not show float as float number like other languages, for example:

$var = 1;
echo ((float) $var);

Output:

1
