method
each
ruby latest stable - Class:
Prime
each(ubound = nil, generator = EratosthenesGenerator.new, &block)public
Iterates the given block over all prime numbers.
Parameters
ubound
Optional. An arbitrary positive number. The upper bound of enumeration. The method enumerates prime numbers infinitely if ubound is nil.
generator
Optional. An implementation of pseudo-prime generator.
Return value
An evaluated value of the given block at the last time. Or an enumerator which is compatible to an Enumerator if no block given.
Description
Calls block once for each prime number, passing the prime as a parameter.
ubound
Upper bound of prime numbers. The iterator stops after it yields all prime numbers p <= ubound.
