LibraryUnload   (Built-in Mathematica Symbol)
LibraryUnload[lib] unloads all functions that have been loaded from a Wolfram Library, then it unloads the library.
LibraryFunctionError   (Built-in Mathematica Symbol)
LibraryFunctionError[name, code] represents an error returned from a LibraryFunction.
Machine-Precision Numbers   (Mathematica Tutorial)
Whenever machine-precision numbers appear in a calculation, the whole calculation is typically done in machine precision. Mathematica will then give machine-precision numbers ...
Limit   (Built-in Mathematica Symbol)
Limit[expr, x -> x_0] finds the limiting value of expr when x approaches x_0.
Return   (Built-in Mathematica Symbol)
Return[expr] returns the value expr from a function. Return[] returns the value Null.
