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. Any fractional part of the number is converted to a time of day, starting at midnight.ĬDate recognizes date formats according to the locale setting of your system. When converting a number to a date, the whole number portion is converted to a date. CDate recognizes date literals and time literals as well as some numbers that fall within the range of acceptable dates. Use the IsDate function to determine if date can be converted to a date or time. Also, Fix and Int always return a value of the same type as is passed in. CInt and CLng differ from the Fix and Int functions, which truncate, rather than round, the fractional part of a number. For example, 0.5 rounds to 0, and 1.5 rounds to 2. When the fractional part is exactly 0.5, CInt and CLng always round it to the nearest even number. For example, when you use CCur, different decimal separators, different thousand separators, and various currency options are properly recognized depending on the locale setting of your computer. You should use the data-type conversion functions instead of Val to provide internationally aware conversions from one data type to another. For example, use CCur to force currency arithmetic in cases where single-precision, double-precision, or integer arithmetic normally would occur. In general, you can document your code using the data-type conversion functions to show that the result of some operation should be expressed as a particular data type rather than the default data type. If the expression passed to the function is outside the range of the data type being converted to, an error occurs. Returns for CStr depend on the expression argument. For numbers with 28 decimal places, the range is The function name determines the return type as shown in the following: The required expressionargument is any string expression or numeric expression. Each function coerces an expression to a specific data type.
