UInt64 Function
Syntax
Number {Unsigned 64-bit Integer} UInt64(Any Type value)
Return Value
This function converts a type to a number with a representation of Unsigned 64-bit Integer. The function cannot convert a container or array data type to a number, and cannot convert an empty string to a number.
Note
The TestStand Sequence Analyzer reports an error if an expression specifies to convert a string value and the string value is empty at edit-time. You can use the
#NoValidation
function to instruct the analyzer to ignore the
UInt64
expression.
For example:
Locals.MyNumber = #NoValidation(UInt64(Locals.MyEmptyString))
.
Note
Do not use this to create a 64-bit integer constant. Use the ui64 suffix instead, for example, 18446744073709551615ui64 or 0xffffffffffffffffui64. For more information about floating point constants, you can view the
