ACSUtils defines constants that represent minimum and maximum values that can be stored in memory blocks (variables) of various sizes.

ACS `int`

is a signed 32-bit integer. Unsigned ints don't exist in ACS, so `UINT_MAX`

can't be expressed.

`INT_MIN = -2147483648 (-0x80000000)`

– minimum value`INT_MAX = 2147483647 (0x7fffffff)`

– maximum value

16-bit integers are also known as shorts.

`SHORT_MIN = -32768`

– minimum value of signed short`SHORT_MAX = 32676`

– maximum value of signed short`USHORT_MAX = 65535`

– maximum value of unsigned short (minimum is 0)

8-bit integers are also known as bytes.

`BYTE_MIN = -128`

– minimum value of signed byte`BYTE_MAX = 127`

– maximum value of signed byte`UBYTE_MAX = 255`

– maximum value of unsigned short (minimum is 0)

Fixed-point numbers are 32-bit integers and have the same limits as `int`

(`INT_MIN`

and `INT_MAX`

). But to enable strict typing, there are separate limit constants for `fixed`

:

`FIXED_MIN = (fixed)-0x80000000`

– minimum value (-32768.0)`FIXED_MAX = (fixed) 0x7fffffff`

– maximum value (slightly less than 32767.99999)
