Integers

Integers are whole numbers and are equivalent in range as your C compiler’s long value. On many common machines, such as Intel Pentiums, that means a 32-bit signed integer with a range between –2,147,483,648 to +2,147,483,647. Integers can be written in decimal, hexadecimal (prefixed with 0x), and octal notation (prefixed with 0), and can include +/- signs.

Some examples of integers include

240000

0xABCD

007

-100

Note: As integers are signed, the right shift operator in PHP always does a signed shift.

Floating-Point Numbers

Floating-point numbers (also known as real numbers) represent real numbers and are equivalent to your platform C compiler’s double data type. On common platforms, the data type size is 8 bytes and it has a range of approximately 2.2E–308 to 1.8E+308. Floating-point numbers include a decimal point and can include a +/- sign and an exponent value.

Examples of floating-point numbers include

3.14

+0.9e-2

-170000.5
