When mixed with other data types in expressions, the resulting data type follows the rules shown in Numeric type promotion in expressions. An attempt to put an integer value of a larger storage size into a location of a smaller size fails if the value cannot be stored in the smaller-size...
A C++ (or C) implementation can define the size of a type in bytes sizeof(type) to any value, as long as the expression sizeof(type) * CHAR_BIT evaluates to the number of bits enough to contain required ranges, and the ordering of type is still valid (e.g. sizeof(int) <= size...
Real Data Type Real is an approximate number data type equivalent to a float(24) used to store a floating-point number Range of values: – 3.40E + 38 to -1.18E – 38, 0 and 1.18E – 38 to 3.40E + 38 Storage size: 4 Bytes -- realDECLARE@MyRealreal=0.111111111111111111111111111111111111...
The size of theinttype is 4 bytes (32 bits). The minimal value is -2 147 483 648, the maximal one is 2 147 483 647. uint The unsigned integer type isuint. It takes 4 bytes of memory and allows expressing integers from 0 to 4 294 967 295. ...

The types__int8,__int16, and__int32are synonyms for the ANSI types that have the same size, and are useful for writing portable code that behaves identically across multiple platforms. The__int8data type is synonymous with typechar,__int16is synonymous with typeshort, and__int32is synon...
