Convert to an unsigned int32 (on the stack as int32) and throw an exception on overflow. Base instruction 0x88 conv.ovf.u4.un: Convert unsigned to an unsigned int32 (on the stack as int32) and throw an exception on overflow. Base instruction 0xBA conv.ovf.u8: Convert to an unsigned int64 (on the stack as int64) and throw an exception on overflow.
The integer is: 16777217 The float is: 16777216.000000 Their equality: 1 Note that 1 represents equality in the last line above. This odd behavior is caused by an implicit conversion of i_value to float when it is compared with f_value. The conversion causes loss of precision, which makes the values equal before the comparison. Important takeaways:
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.
Runtime exception handling method in C# is inherited from Java and C++. ... Int32: integer ... unsigned integer 0 through 255 8-bit (1-byte) 0:
The actual sizes of short int, int, and long int are available as the constants short max int, max int, and long max int etc. ^b Commonly used for characters. ^c The ALGOL 68, C and C++ languages do not specify the exact width of the integer types short , int , long , and ( C99 , C++11 ) long long , so they are implementation-dependent.
The Java virtual machine's set of primitive data types consists of: [12] byte, short, int, long, char (integer types with a variety of ranges) float and double, floating-point numbers with single and double precisions; boolean, a Boolean type with logical values true and false; returnAddress, a value referring to an executable memory address ...
Integer are reference objects, on the surface no different from List, Object, and so forth. To convert from an int to an Integer, one had to "manually" instantiate the Integer object. As of J2SE 5.0, the compiler will accept the last line, and automatically transform it so that an Integer object is created to store the value 9. [2]
A constant unsigned integer variable can be declared as: const unsigned int x ; where const is a type qualifier, which the qualified type of x is const unsigned int and the unqualified type is unsigned int .
