Summary

0000386: int32 and real can't be unified

Description

Hello, With the svn version of frama-c and jessie, I have the following problem: an integer cannot be promoted to real inside a function call. The function \pow takes 2 real numbers. If I give it an int32. Jessie fails to type it.

Additional Information

# pragma JessieFloatModel(strict) double malcolm1() { double A; A=2.0; /*@ assert A==2.; */ /*@ ghost int i = 1; */ /*@ loop invariant A== \pow(2.,i) && @ 1 <= i <= 53; @ loop variant (53-i); */ while (A != (A+1)) { A*=2.0; /*@ ghost i++; */ } /*@ assert A== 0x1.p53; */ }
