They - produce uniformly distributed numbers in the range <c>0.0 - =< X < 1.0</c> that are as close to random real - numbers as Normalized IEEE 754 Double Precision allows. - Because the random real number exactly <c>0.0</c> is - infinitely improbable they will never return exactly - <c>0.0</c>. </p><p> These properties are useful when you - need to call for example <c>math:log(X)</c> or <c>1 / - X</c> on a random value <c>X</c>, since that will never - fail with a number from these new functions. </p> - <p> - Own Id: OTP-13764 Aux Id: PR-1574 </p> - </item> - <item> - <p> - Added maps:iterator/0 and maps:next/1 to be used for - iterating over the key-value associations in a map.</p> - <p> - Own Id: OTP-14012</p> - </item> - <item> - <p>Changed the default behaviour of <c>.erlang</c> - loading: <c>.erlang</c> is no longer loaded from the - current directory. <c>c:erlangrc(PathList)</c> can be - used to search and load an <c>.erlang</c> file from user - specified directories.</p> <p><c>escript</c>, - <c>erlc</c>, <c>dialyzer</c> and <c>typer</c> no longer - load an <c>.erlang</c> at all.</p> - <p> - *** POTENTIAL INCOMPATIBILITY ***</p> - <p> - Own Id: OTP-14439</p> - </item> - <item> - <p> - Added new uri_string module to stdlib for handling URIs - (RFC 3986).</p> - <p> - Own Id: OTP-14496</p> - </item> - <item> - <p> - Update Unicode specification to version 10.0.</p> - <p> - Own Id: OTP-14503</p> - </item> - <item> - <p><c>filelib:wildcard()</c> now allows characters with a - special meaning to be escaped using backslashes.</p> - <p>This is an incompatible change, but note that the use - of backslashes in wildcards would already work - differently on Windows and Unix. Existing calls to - <c>filelib:wildcard()</c> needs to be updated.

The only option is <c>chars_limit</c>, which is - used for limiting the number of returned characters. The - limit is soft, which means that the number of returned - characters exceeds the limit with at most a smallish - amount. If the limit is set, the functions - <c>format/3</c> and <c>fwrite/3</c> try to distribute the - number of characters evenly over the control sequences - <c>pPswW</c>. Furthermore, the control sequences - <c>pPwP</c> try to distribute the number of characters - evenly over substructures. </p> <p> A modification of the - control sequences <c>pPwW</c> is that even if there is no - limit on the number of returned characters, all - associations of a map are printed to the same depth. The - aim is to give a more consistent output as the order of - map keys is not defined. As before, if the depth is less - than the number of associations of a map, the selection - of associations to print is arbitrary. </p> - <p> - Own Id: OTP-14983</p> - </item> - <item> - <p> Add functions <c>ordsets:is_empty/1</c> and - <c>sets:is_empty/1</c>. </p> - <p> - Own Id: OTP-14996 Aux Id: ERL-557, PR-1703 </p> - </item> - <item> - <p>External funs with literal values for module, name, - and arity (e.g. <c>erlang:abs/1</c>) are now treated as - literals. That means more efficient code that produces - less garbage on the heap.</p> - <p> - Own Id: OTP-15003</p> - </item> - <item> - <p> - sys:statistics(Pid,get) did not report 'out' messages - from gen_server. This is now corrected.</p> - <p> - Own Id: OTP-15047</p> - </item> - <item> - <p> - A sys debug function can now have the format - {Id,Fun,State} in addition to the old {Fun,State}.
