TFloatHash instance with the default
capacity and load factor.

TFloatHashSet(int initialCapacity, TFloatHashingStrategy strategy) - Creates a new
TFloatHash instance whose capacity
is the next highest prime above initialCapacity + 1
unless that value is already prime.

TFloatHashSet(int initialCapacity, float loadFactor) - Creates a new
TFloatHashSet instance with a prime
capacity equal to or greater than initialCapacity and
with the specified load factor.
|
TFloatHashSet(int initialCapacity, float loadFactor, TFloatHashingStrategy strategy) - Creates a new
TFloatHash instance with a prime
value at or near the specified capacity and load factor.
