Function 'eq'
Afficher commentaires plus anciens
When I use 'eq' function or '==' I get strange results.
eq((0.6-0.2-0.2),0.2)
ans =
0
Please tell me why Matlab does not return true? What is not correct?

Please read this faq: http://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F
In brief, note that .6 -.2 -.2 not equal to .2:
sprintf('%.17f',0.6-0.2-0.2)
ans =
0.19999999999999996
