Convert to an unsigned int64 (on the stack as int64) and throw an exception on overflow. Base instruction 0x89 conv.ovf.u8.un: Convert unsigned to an unsigned int64 (on the stack as int64) and throw an exception on overflow. Base instruction 0x76 conv.r.un: Convert unsigned integer to floating-point, pushing F on stack. Base instruction 0x6B ...
In computer science, an integer literal is a kind of literal for an integer whose value is directly represented in source code.For example, in the assignment statement x = 1, the string 1 is an integer literal indicating the value 1, while in the statement x = 0x10 the string 0x10 is an integer literal indicating the value 16, which is represented by 10 in hexadecimal (indicated by the 0x prefix).
C and C++ perform such promotion for objects of Boolean, character, wide character, enumeration, and short integer types which are promoted to int, and for objects of type float, which are promoted to double. Unlike some other type conversions, promotions never lose precision or modify the value stored in the object. In Java:
In addition to the assumption about bit-representation of floating-point numbers, the above floating-point type-punning example also violates the C language's constraints on how objects are accessed: [3] the declared type of x is float but it is read through an expression of type unsigned int.

The DWARF file format uses both unsigned and signed LEB128 encoding for various fields. [2] LLVM, in its Coverage Mapping Format [8] LLVM's implementation of LEB128 encoding and decoding is useful alongside the pseudocode above. [9].NET supports a "7-bit encoded int" format in the BinaryReader and BinaryWriter classes. [10]
An integral type with n bits can encode 2 n numbers; for example an unsigned type typically represents the non-negative values 0 through 2 n − 1. Other encodings of integer values to bit patterns are sometimes used, for example binary-coded decimal or Gray code , or as printed character codes such as ASCII .
unsigned int as a hexadecimal number. x uses lower-case letters and X uses upper-case. o: unsigned int in octal. s: null-terminated string. c: char . p: void* (pointer to void) in an implementation-defined format. a, A: double in hexadecimal notation, starting with 0x or 0X. a uses lower-case letters, A uses upper-case letters.
