Jun 25, 2014 The result shows date and time as “General Date”. This should show “Short Date” It also shows multiple years like 2012, 2013, and 2014 for same date that was selected by user. If the user select same date for “Start Date” and “End Date”; system doesn’t show any data. Because a Date/Time value is stored as a double-precision number, you may receive incorrect formatting results when you try to manipulate Date/Time values in an expression. This article demonstrates how to create expressions and custom functions for displaying specific dates and for calculating time intervals.
Each function coerces an expression to a specific data type.
Syntax
CBool(expression)
CByte(expression)
CCur(expression)
CDate(expression)
CDbl(expression)
CDec(expression)
CInt(expression)
CLng(expression)
CSng(expression)
CStr(expression)
CVar(expression)
The required expressionargument is any string expression or numeric expression.
Return Types
The function name determines the return type as shown in the following:
Function | Return Type | Range for expression argument |
|---|---|---|
CBool | Boolean | Any valid string or numeric expression. |
CByte | Byte | 0 to 255. |
CCur | Currency | -922,337,203,685,477.5808 to 922,337,203,685,477.5807. |
CDate | Date | Any valid date expression. |
CDbl | Double | -1.79769313486231E308 to |
CDec | Decimal | +/-79,228,162,514,264,337,593,543,950,335 for zero-scaled numbers, that is, numbers with no decimal places. For numbers with 28 decimal places, the range is |
CInt | Integer | -32,768 to 32,767; fractions are rounded. |
CLng | Long | -2,147,483,648 to 2,147,483,647; fractions are rounded. |
CSng | Single | -3.402823E38 to -1.401298E-45 for negative values; 1.401298E-45 to 3.402823E38 for positive values. |
CStr | String | Returns for CStr depend on the expression argument. |
CVar | Variant | Same range as Double for numerics. Same range as String for non-numerics. |
Remarks
Microsoft Access Convert Date To Quarter
If the expression passed to the function is outside the range of the data type being converted to, an error occurs.
In general, you can document your code using the xmlns:friendlytitlelookup='urn:FriendlyTitleLookup' xmlns:hrefappend='urn:HrefExtensions'>You should use the xmlns:friendlytitlelookup='urn:FriendlyTitleLookup' xmlns:hrefappend='urn:HrefExtensions'>When the fractional part is exactly 0.5, CInt and CLng always round it to the nearest even number. For example, 0.5 rounds to 0, and 1.5 rounds to 2. CInt and CLng differ from the Fix and Int functions, which truncate, rather than round, the fractional part of a number. Also, Fix and Int always return a value of the same type as is passed in.
Microsoft Access Convert Date To Number
Use the IsDate function to determine if date can be converted to a date or time. CDate recognizes date literals and time literals as well as some numbers that fall within the range of acceptable dates. When converting a number to a date, the whole number portion is converted to a date. Any fractional part of the number is converted to a time of day, starting at midnight.
CDate recognizes date formats according to the locale setting of your system. The correct order of day, month, and year may not be determined if it is provided in a format other than one of the recognized date settings. In addition, a long date format is not recognized if it also contains the day-of-the-week string.

A CVDate function is also provided for compatibility with previous versions of Visual Basic. The syntax of the CVDate function is identical to the CDate function, however, CVDate returns a Variant whose subtype is Date instead of an actual Date type. Since there is now an intrinsic Date type, there is no further need for CVDate. The same effect can be achieved by converting an expression to a Date, and then assigning it to a Variant. This technique is consistent with the conversion of all other intrinsic types to their equivalent Variant subtypes.

Note: The CDec function does not return a discrete data type; instead, it always returns a Variant whose value has been converted to a Decimal subtype.
