Detailed Description

This validator is used to verify that a parameter represents a valid integer.

Note that the validator supports 64 bits integers by default. You can reduce the size by defining your parameter with a range as required by your application.

The value is checked for overflows on a signed 64 bits value.

The function supports decimal numbers by default (base 10). An introducer can be used to change the base as follow:

• 0x... – hexadecimal numbers
• 0d... – decimal numbers
• 0o... – octal numbers
• 0b... – binary numbers

Note that a number that starts with 0 does not represent an octal number with the existing algorithm.
