Description
Indicates the radix in exponent
representation.
Indicates whether or not the result of an
add operation is rounded off.
The meaning of this macro definition is as
follows:
(1) When result of add operation is
(2) When result of add operation is
(3) When nothing is specified: –1
The rounding-off and rounding-down
methods are implementation-defined.
Indicates whether or not a guard bit is
used in multiply operations.
The meaning of this macro definition is as
follows:
(1) When guard bit is used: 1
(2) When guard bit is not used: 0
Indicates whether or not floating-point
values are normalized.
The meaning of this macro definition is as
follows:
(1) When normalized: 1
(2) When not normalized: 0
Indicates the maximum value that can be
represented as a float type floating-point
value.
Indicates the maximum value that can be
represented as a double type floating-
point value.
Indicates the maximum value that can be
represented as a long double type
floating-point value.
rounded off: Positive value
rounded down: 0
