0.1 float is greater than 0.1 double. I expected it to be false [duplicate]

Answer 1

Since it can't be exactly represented, comparing 1/10 in base 2 is like comparing 1/7 in base 10.

1/7 = 0.142857142857... but comparing at different base 10 precisions (3 versus 6 decimal places) we have 0.143 > 0.142857.
