A floating-point is a representation of real numbers that can support wide range of values. PHP use IEEE 754 double precision format. Floating-point numbers have limited precision. Floating–point has decimal values and fractional part.
A floating-point numbers is also known as double, float or real numbers. The size of floating values depends upon the platform we use and also a maximum of ~1.8e308 with a precision of roughly 14 decimal digits is a common value.
