TINYINT

The TINYINT data type is used for storing very small whole numbers.

Syntax

TINYINT

The storage of TINYINT variables is based on 1 byte of signed data ( = 8 bits ).

The value range is from -128 to +127.

TINYINT variables can be initialized with integer literals:

MAIN
  DEFINE i TINYINT
  LET i = 101
  DISPLAY i 
END MAIN

When assigning a whole number that exceeds the TINYINT range, the overflow error -8097 will be raised.

TINYINT variables are initialized to zero in functions, modules and globals.

The TINYINT variables cannot be NULL.

Data type conversion can be controlled by catching the runtime exceptions. For more details, see Handling type conversion errors.
