Conversions from unsigned integral types
Conversions from unsigned integral types - Microsoft Learn
When the compiler converts an unsigned integer to a floating-point type, if the original value isn't representable exactly in the result type, ...
The resulting value is the smallest unsigned integer type congruent to the source integer. If the value cannot be represented by the new type, truncation or ...
Conversions from signed integral types - Microsoft Learn
It assumes the char type is signed by default. If you use a compile-time option to change the default for the char type to unsigned, the ...
4. Type Conversions - C in a Nutshell [Book] - O'Reilly
Any two unsigned integer types have different conversion ranks. If one is wider than the other, then it has a higher rank. Each signed integer type has the same ...
Conversions from Unsigned Integral Types style. Is this style good?
That's a trick to give the maximum (not minimum) value of an unsigned type. Conversion from a signed value uses modular arithmetic to give a ...
Implicit conversions - cppreference.com
[edit] Integer conversions · if the target type can represent the value, the value is unchanged · otherwise, if the target type is unsigned, the ...
INT02-C. Understand integer conversion rules - Confluence
If both operands have the same type, no further conversion is needed. · If both operands are of the same integer type (signed or unsigned), the operand with the ...
A simple way to describe the conversion rules is as follows: each integer type is ranked in the order char, short, int, long, long long, with the ...
Integer Conversion (GNU C Language Manual) - GNU.org
The process of conversion to a wider type is straightforward: the value is unchanged. The only exception is when converting a negative value (in a signed type, ...
Can someone explain the history around implicit conversion when ...
The rule in C is that if you use two integer types together, and they are both the same rank, but one of the types is unsigned, then you convert ...
If the unsigned integer type is equal or smaller than the signed integer type, then the value is converted to unsigned by adding to it one greater than the ...
Usual arithmetic conversions - cppreference.com
If T1 and T2 are the same type, C is that type. · Otherwise, if T1 and T2 are both signed integer types or both unsigned integer types, C is the ...
Generic conversion between signed and unsigned integer types
Let's assume that I have a generic function foo() which returns an unsigned integer whose type is inferred from the context: func foo
Usual arithmetic conversions - IBM
Otherwise, if both operands have signed integer types or both have unsigned integer types, the type at a lower integer conversion rank is converted to the type ...
C++ integral promotions and sonar rules
It seems that Sonar works with the types after implicit conversions / integral promotion is applied → the uint16_t b automatically becomes int ...
Integral promotion is the implicit conversion of enumerated types, signed or unsigned varieties of char, short int or bit-field types to either signed int or ...
Integer Conversions (The GNU C Library)
Specifies that the argument is a int n _t or int_least n _t (which are the same type), for conversions taking signed integers, or uint n _t or uint_least n _t ( ...
Implicit conversions · Integral promotions convert the small integral types to a larger integral type. · Larger char types (wchar_t, char16_t, ...
Type Conversions | RC Learning Portal
The hierarchy, from lowest to highest, is bool -> char -> short int -> int -> unsigned int -> long -> unsigned -> long long -> float -> double - ...
4.7 Integral conversions [conv.integral]
A prvalue of an integer type can be converted to a prvalue of another integer type. A prvalue of an unscoped enumeration type can be converted to a prvalue ...
