Point taken. \eq_float is indeed overloaded to take into account both 
float and double in Frama-C (and the ACSL document is inaccurate on this 
point ;-).

But x (a floating point variable coming directly from C), as well as 
\round_double(\NearestEven,y+z) could namely be infinities. It thus 
makes sense to use \eq_float to compare them.
