We have already seen integers (int) and strings
(string) being used in several examples, but the third basic
type, float, is new. A float, also called a real
number or a floating-point number, is different from an
integer in that it can have a fraction part:
6.783 // This is a floating-point number
17 // This is an integer
17.0 // This is a floating-point number
Note that Pike differentiates between integer and floating-point
numbers that happen to be equal to an integer. If you write
17 in a Pike program you get an integer, and if you write
17.0 you get a floating-point number. Inside the computer
they look completely different.
You can define variables like this:
int number_of_monkeys; // An integer variable
float z = -16.2; // A floating-point variable
string file_name; // A string variable
mixed x; // A variable for anything
The data type mixed means "any type of value".
