(b) Conversion between decimal and internal representation
iii. Notes on operations on special values
This section describes the specifications for conversions between floating-point numbers in
a source program and internal representation, and conversion by library functions between
the decimal representation of floating-point numbers in ASCII strings and their internal
representation.
i. When converting from decimal to internal representation, the decimal value is first
The following are notes on operations on special values (zero, infinity, and not-a-
number).
a. The sum of a positive zero and a negative zero is a positive zero.
b. The difference between two zeros of the same sign is a positive zero.
c. The result of operations that include not-a-number in one or both operands is always
d. In comparative operations, positive zeros and negative zeros are processed as equal.
e. The result of comparative operations or equivalence operations where either one or
converted to its normalized form. The normalized form of a decimal value is

If a decimal value cannot be converted to its normalized form, an overflow or
underflow occurs. If the decimal representation contains more valid numerals than
the normalized form, the trailing digits are truncated. In this case, a warning level
error message is output at compilation and the corresponding error number is set in
errno when the program is executed. For conversion to its normalized form, the
original decimal representation must, in the form of an ASCII string, be within 511
characters. If not, an error occurs at compilation and the corresponding error
number is set in errno when the program is executed. When converting from
internal representation to decimal, the value is first converted to the normalized
decimal form, then converted to an ASCII string according to the specified format.
