ANA
ANA offers the following numerical data types:
BYTE
BYTE number requires one byte of storage, and can have any
integer value between 0 and 255 (#MAX_BYTE -- #MAX_BYTE --
inclusive).
(2^8 - 1),
inclusive.
WORD
WORD number requires two bytes of storage, and can have any
integer value between -32768 (#MIN_WORD --
#MIN_WORD) and +32767 (#MAX_WORD -- #MAX_WORD)
(2^15 - 1),
inclusive.
LONG
LONG number requires four bytes of storage, and can have any
integer value between -2147483648 (#MIN_LONG --
#MIN_LONG) and +2147483647 (#MAX_LONG -- #MAX_LONG)
(2^31 - 1),
inclusive.
FLOAT
FLOAT number requires four bytes of storage, and has a
single-precision floating-point value. The meaning of "single
precision" depends on the way that floating-point numbers are
represented inside your computer. On all computers, these values have
at least 6 significant digits, and may have a magnitude at least as
large as
10^37
and at least as small as (when larger than zero)
10^-37.
The largest absolute value representable on your machine as a
FLOAT is equal to #MAX_FLOAT (#MAX_FLOAT). The
smallest representable non-zero absolute value is equal to
#MIN_FLOAT (#MIN_FLOAT).
On machines that comply with the IEEE 754-1985 standard for binary
floating-point arithmetic, values of type FLOAT may have the
value zero and also values between about
7*10^-46 (2^-150)
and
3*10^38 (2^128),
as well as the special values Inf (too large for this data
type) and NaN (Not-A-Number, for undefined results such as the
square root of a negative number; see ISNAN).
DOUBLE
DOUBLE number requires eight bytes of storage, and has a
double-precision floating-point value. As for FLOAT values, the
precision reached depends on your computer. These values have at least
10 significant digits, and have a range of magnitudes at least as large
as that of a FLOAT value. The largest and smallest representable
absolute non-zero values of type DOUBLE are #MAX_DOUBLE
(#MAX_DOUBLE) and #MIN_DOUBLE (#MIN_DOUBLE).
On computers that comply with the IEEE 754-1985 standard for binary
floating-point arithmetic, values of type DOUBLE may have the
value zero and also values between about
1*10^-308 (2^-1075)
and
4*10^308 (2^1025),
as well as the special values Inf (too large for this data
type) and NaN (Not-A-Number, for undefined results such as the
square root of a negative number).
On computers that comply with the IEEE 754-1985 standard, the ratio
1.0/0.0 yields the value Inf (infinity), and that value is
available in the global variable #INFTY. On computers that do
not allow division by (floating-point) zero, #INFTY is equal to
#MAX_FLOAT.
