Standard Data Types

Question

I am looking for information regarding data type standardization.

Take for example a double precision floating point value:

STANDARDIZATION: IEEE 754

JavaScript: Number

Java: double

C#: double / System.Double

C/C++: double (compiler dependant implementation)

The example above illustrates implementations of a double precision floating point value in different programming languages. I would like to know if there is any standardization (for example; ISO, IEEE, ECMA, etc.) of other common data types, specifically:

• signed and unsigned 8bit, 16bit, 32bit and 64bit integers
• single, double and currency/decimal floating point values
• ascii and unicode characters
• boolean
• string

I have already taken a look at ISO/IEC 11404 but I didn't find it particlarly helpful

Answer 1

Some of your types are addressed here...

The Common Language Specification is standardized in ECMA-335 and implemented in many languages for Microsoft .NET. It was intentionally designed without unsigned integral types. However, the .NET Framework does include them.
