A ##[[KeyPgUlong|Ulong]]## value.

{{fbdoc item="desc"}}
The ##**Culng**## function rounds off the decimal part and returns a 32 bit ##[[KeyPgUlong|Ulong]]## value. The function does not check for an overflow. The name can be explained as 'Convert to Unsigned ""LoNG""'.

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