Description:
Convert a string, a number or a date to a 64-bit long integer.
Syntax:
long(stringExp)
long(numberExp)
long(dateExp)
Note:
The value of parameter stringExp must be a string that consists of a long integer which has 64 bits or less. For a value with more than 64 bits, the result of long(stringExp) is imprecise and its fractional part, if any, will be truncated.
The value of parameter numberExp must be a long integer which has 64 bits or less. For a value with more than 64 bits, the result of long(numberExp) is imprecise and its fractional part, if any, will be truncated.
Parameter:
|
stringExp |
The string expression you want to convert as a long integer. |
