How to say "negligible" in Japanese

• あってなきがごとき
  expressionCovers 'negligible' meaning virtually nonexistent: something so slight it can be treated as if it did not exist. Suits a presence or influence that is as good as nothing. A less common choice.
• ごくわずか
  expression, na-adjectiveUse for the quantitative sense of 'negligible': a difference, cost, or amount so small it can be ignored. It plainly states extreme smallness of quantity and is usually written in kana alone.
  両者りょうしゃの間あいだには、あったとしても、相違そういはごくわずかである。↗

  There is little, if any, difference between the two.
• 微少びしょう
  na-adjective, no-adjectiveMeans very small or slight in amount; as a rendering of 'negligible' it is a marginal, less common choice, stressing smallness rather than insignificance, so 'slight' or 'trifling' is often the closer sense.
• 取るに足らないとるにたらない
  expression, i-adjectiveAn idiomatic expression for 'negligible' in the sense of not worth considering: insignificant, inconsequential, beneath attention. It judges importance rather than measuring quantity, fitting a trivial detail or difference.
  戦争せんそうの際さいには歩兵ふひょうは取とるに足たらないものだ。↗

  The infantry soldier is only a pawn in the game of war.

Choose 「ごくわずか」 for a negligibly small amount, 「取るに足らない」 for something too trivial to bother with, 「あってなきがごとき」 for what is as good as nonexistent, and 微少 mainly for 'very small, slight'.
