C30 User’s Guide
Implementation-Defined Behavior for Integers is covered in section G.3.5 of the ANSI
C Standard.
The following table describes the amount of storage and range of various types of
integers: (ISO 6.1.2.5)
TABLE A-2:
What is the result of converting an integer to a shorter signed integer, or the result of
converting an unsigned integer to a signed integer of equal length, if the value cannot
be represented? (ISO 6.2.1.2)
There is a loss of significance. No error is signaled.
What are the results of bitwise operations on signed integers? (ISO 6.3)
Shift operators retain the sign. Other operators act as if the operand(s) are unsigned
integers.
What is the sign of the remainder on integer division? (ISO 6.3.5)
+
What is the result of a right shift of a negative-valued signed integral type? (ISO 6.3.7)
The sign is retained.
Implementation-Defined Behavior for Floating Point is covered in section G.3.6 of the
ANSI C Standard.
Is the scaled value of a floating constant that is in the range of the representable value
for its type, the nearest representable value, or the larger representable value immedi-
ately adjacent to the nearest representable value, or the smallest representable value
immediately adjacent to the nearest representable value? (ISO 6.1.3.1)
The nearest representable value.
