In VB does currency and integer datatype almost resemble the same thing?

What is the difference exactly?

What is the actual use of the currency Data Type?

Generally, integers are 2-byte values from -32.768 to 32.767 ( signed integers ).
Instead, currency is a 8-byte value that is used for currency values with high precision. Their range is -922.3372036854775808 - 922.3772036854775807

The important thing about the currency data type is that it will never lose/round digits as it is stored as a pure binary number in memory as opposed to a mantissa/exponent pair. A double precision float is actually accurate to a lower number of decimal places than it holds, which saves memory but would not be suitable for transaction & financial uses.

lol. I personally favour 42. How long is a piece of (null terminated) string?

Three years ago, I bought a Piter Norton book for Visual Basic 6.0. I heared that it is a very good book, so I looked in and found about data types in vb.
That's it.

The "size" of an integer is purely implementation specific, a matter of definition related to a very limited set of circumstances. I suspect that your book actually tells you that, particularly if it was actually authored by THE Peter Norton. I don't wish to harp on this unduly, but one must BE CAREFUL with information they impart. There is no sin in accompanying your information with caveats and qualifications because absolutes are so rare. It is, indeed, usually better that one do so.

Ok, nevermind as always, probably you are right... I give up...

I perceive that your feelings are hurt. I apologize for that. It is my own personal desire that this forum serve primarily as a place that novices may receive accurate and useful answers to their questions. In all honesty, I have given out bum information. Probably we all have. I would still rather see a reasonable amount of care taken, despite the fact that the forum is not universally viewed in that light. This personal desire sometimes outweighs my desire to be socially acceptable to the membership as a whole.
