I was checking a possible inconsistency on ActiveModel and I found situations where comparing BigDecimal to Float differs to comparing Float to BigDecimal.

I have create a simple ruby script to exemplify the problem. The script is attach to this issue and output is as follows:

Instance number 706.05
###########
Instance number 706.06
Inconsistence:
0.70606E3 > 706.06
706.06 < 0.70606E3

Inconsistence:
0.70606E3 <= 706.06
706.06 >= 0.70606E3

###########
Instance number 706.07
Inconsistence:
0.70607E3 < 706.07
706.07 > 0.70607E3

Inconsistence:
0.70607E3 >= 706.07
706.07 <= 0.70607E3

###########
Instance number 706.08
