Results for: "String# "

Since int is already an Integer, this always returns true.

Returns the smallest number than or equal to int in decimal digits (default 0 digits).

Precision may be negative. Returns a floating point number when ndigits is positive, self for zero, and truncate up for negative.

1.truncate        #=> 1
1.truncate(2)     #=> 1.0
15.truncate(-1)   #=> 10

Returns the remainder after dividing big by numeric as:

x.remainder(y) means x-y*(x/y).truncate

Examples

5.remainder(3)    #=> 2
-5.remainder(3)   #=> -2
5.remainder(-3)   #=> 2
-5.remainder(-3)  #=> -2

-1234567890987654321.remainder(13731)      #=> -6966
-1234567890987654321.remainder(13731.24)   #=> -9906.22531493148

See Numeric#divmod.

Returns a string containing the representation of int radix base (between 2 and 36).

12345.to_s       #=> "12345"
12345.to_s(2)    #=> "11000000111001"
12345.to_s(8)    #=> "30071"
12345.to_s(10)   #=> "12345"
12345.to_s(16)   #=> "3039"
12345.to_s(36)   #=> "9ix"
78546939656932.to_s(36)  #=> "rubyrules"

Returns 1.

Create the tasks defined by this task lib.

Returns true if the set contains the given object.

Note that include? and member? do not test member equality using == as do other Enumerables.

See also Enumerable#include?

Returns true if the set and the given set have at least one element in common.

e.g.:

require 'set'
Set[1, 2, 3].intersect? Set[4, 5] # => false
Set[1, 2, 3].intersect? Set[3, 4] # => true

Returns true if the set and the given set have no element in common. This method is the opposite of intersect?.

e.g.:

require 'set'
Set[1, 2, 3].disjoint? Set[3, 4] # => false
Set[1, 2, 3].disjoint? Set[4, 5] # => true

Deletes every element that appears in the given enumerable object and returns self.

Returns a string containing a human-readable representation of the set. (“#<Set: {element1, element2, …}>”)

Unlinks (deletes) the file from the filesystem. One should always unlink the file after using it, as is explained in the “Explicit close” good practice section in the Tempfile overview:

file = Tempfile.new('foo')
begin
   ...do something with file...
ensure
   file.close
   file.unlink   # deletes the temp file
end

Unlink-before-close

On POSIX systems it’s possible to unlink a file before closing it. This practice is explained in detail in the Tempfile overview (section “Unlink after creation”); please refer there for more information.

However, unlink-before-close may not be supported on non-POSIX operating systems. Microsoft Windows is the most notable case: unlinking a non-closed file will result in an error, which this method will silently ignore. If you want to practice unlink-before-close whenever possible, then you should write code like this:

file = Tempfile.new('foo')
file.unlink   # On Windows this silently fails.
begin
   ... do something with file ...
ensure
   file.close!   # Closes the file handle. If the file wasn't unlinked
                 # because #unlink failed, then this method will attempt
                 # to do so again.
end

Returns true if any thread has terminated and is ready to be collected.

Waits for specified threads to terminate, and returns when one of the threads terminated.

Returns true if any thread has terminated and is ready to be collected.

Waits for specified threads to terminate, and returns when one of the threads terminated.

The string representation of true is “true”.

Basically the same as ::new. However, if class Thread is subclassed, then calling start in that subclass will not invoke the subclass’s initialize method.

Returns the main thread.

Stops execution of the current thread, putting it into a “sleep” state, and schedules execution of another thread.

a = Thread.new { print "a"; Thread.stop; print "c" }
sleep 0.1 while a.status!='sleep'
print "b"
a.run
a.join
#=> "abc"
