Module Zv.SSource

Sourceval make : string -> t

Construction

Constructing Z by using a private type, create a Z value from string, e.g. from_str "123". Reason behind is to disallow a range of functions that are unsuitable for currency operations. For convenience the function alias make_z can be used.
