C Integer Constants Article 01/25/2023 7 contributors Feedback In this article Syntax See also Aninteger constantis a decimal (base 10), octal (base 8), or hexadecimal (base 16) number that represents an integral value. Use integer constants to represent integer values that can't be changed...
Due tomaximal munch, hexadecimal integer constants ending ineandE, when followed by the operators+or-, must be separated from the operator with whitespace or parentheses in the source: intx=0xE+2;// errorinty=0xa+2;// OKintz=0xE+2;// OKintq=(0xE)+2;// OK ...
Microsoft C also permits the declaration of sized integer variables, which are integral types of size 8-, 16-, 32- or 64-bits. For more information on sized integers in C, seeSized Integer Types. Limits on Integer Constants ConstantMeaningValue ...
Different compilers might define compile-time constants differently. In the following code,c+1is considered a compile-time constant by GCC compilers, but not by the standard C compiler: const int16_t c = 32767; int16_t y = c + 1; ...
. A constant's value must be in the range of representable values for its type. A constant's type determines which conversions are performed when the constant is used in an expression or when the minus sign (-) is applied. This list summarizes the conversion rules for integer constants....
When multiplying integers with a constant value in C, with Zmmul gcc apparently tries to not emmit mul instructions (it may do it for large constants). Instead it tries to implement the operation with some shift and add immediate instructions (which obviously is less optimized than just a sin...
If you want 64-bit integers you have to ask for them by declaring variables as INTEGER(8) and using the proper kind specifier on the constants, such as 3000000000_8. Just using the 64-bit compiler does NOT change the size of any data types. Default integer is still 32-bit. ...
