Ruby Combine Hash Key As Hash + Key and return as array -


suppose have hash

hash = {"123"=>"abc", "124"=>"def"}

i'm expecting output

[["123 - abc", "123"], ["124 - def", "124"]] pass select tag display "123 - abc" , submit id when selected

i came solution

hash.map{|key,value| ["#{key} - #{value}",key]}

but there better way other this?

ruby - How do I merge two hashes into a hash of arrays? -

http://codepad.org/wmyzqlis i'd merge these 2 arrays: a = { :a => 'a', :b => 'b', :d => 'd' } b = { :a => '1', :b => 'b', :c => 'c' } into hash looks this: {:a => ["a", "1"], :b => ["b", "b"], :c => [nil, "c"], :d => ["d", nil] } this doesn't work: p a.merge(b) { |k, v1, v2| [v1, v2] } # {:c=>"c", :a=>["a", "1"], :b=>["b", "b"], :d=>"d"} it's because hash#merge call block duplicate keys. a = { :a => 'a', :b => 'b', :d => 'd' } b = { :a => '1', :b => 'b', :c => 'c' } hash[(a.keys|b.keys).map { |key| [key, [a.fetch(key, nil), b.fetch(key, nil)]] }] # => {:a=>["a", "1"], :b=>["b", "b"], :d=>["d", nil], :c=>...

c++ - Do gcc's __float128 floating point numbers take the current rounding mode into account? -

do arithmetic operations on gcc's __float128 floating point numbers take current rounding mode account? for instance, if using c++11 function std::fesetenv , change rounding mode fe_downward , results of arithmetic operations on __float128 rounded down? is guaranteed __float128 specification? i believe guaranteed operations on __float128 take rounding mode account. according gnu c library documentation floating-point calculations respect rounding mode. according gcc manual __float128 floating type supports arithmetic operations division etc. from deduce, operations on __float128 , rounding mode has be taken account. the gnu c library documentation states: 20.6 rounding modes floating-point calculations carried out internally precision, , rounded fit destination type. ensures results precise input data. ieee 754 defines 4 possible rounding modes: [...] reference: http://www.gnu.org/software/libc/manual/html_node/rounding.html ...
