As linguagens de programação não conseguem fazer esse simples calculo! Por quê?

Expand|Select|Wrap|Line Numbers
  1. print(128.23 - (118.23 + 10)
  2. echo 128.23 - (118.23 + 10);
  3. console.log(128.23 - (118.23 + 10.00))
  4.  
Para este teste, usei PHP, Python e JavaScript e todas me retornaram o mesmo valor
Ao invés de me retornarem um 0 ou até 0.00, me retornaram -2.842170943040401e-14

Alguém consegue me explicar o porquê disto acontecer?
