Description
When we have an expression "real1" + "real2" in the form where real1 and real2 are fields with real numbers
and real1 = -5.1
and real2 = 1.2
the result should be -3.9 but it is -3.899999999999995
For positive numbers, it works correctly and also when real1 = -5.2 or -5.3

Research direction
Reproduce the mobile form expression with real1 = -5.1 and real2 = 1.2, then compare it with the listed positive and other negative values. Trace the real-number expression evaluation path; done means the expression produces the expected -3.9 result without breaking the other cases.
