a numeric, string, or pointer expression to cast to a ##[[KeyPgUlongint|Ulongint]]## value

any numeric, string, or pointer data type

A ##[[KeyPgUlongint|Ulongint]]## value.

{{fbdoc item="desc"}}
The ##**Culngint**## function rounds off the decimal part and returns a 64-bit ##[[KeyPgUlongint|Ulongint]]## value. The function does not check for an overflow, and results are undefined for values which are less than ##0## or larger than ##18## ##446## ##744## ##073## ##709## ##551## ##615##. Additionally, casts from floating-point expressions are currently not guaranteed to work for values higher than ##2^63## (##9## ##223## ##372## ##036## ##854## ##775## ##808##).

The name can be explained as 'Convert to Unsigned ""LoNG INTeger""'.

If the argument is a string expression, it is converted to numeric by using ##[[KeyPgValulng|Valulng]]##.
