== Synopsis

Declared in `<bslstl_unorderedmap.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
void
max_load_factor(float newMaxLoadFactor);
----

== Description

Set the maximum load factor of this unordered map to the specified `newMaxLoadFactor`. If `newMaxLoadFactor < loadFactor()`, this operator will cause an immediate rehash (in violation of the C++11 standard); otherwise, it has a constant‐time cost. The behavior is undefined unless `0 < newMaxLoadFactor`.
