This might be an issue in mpfr and not GCC if I read GCC's code correctly. 
Depending on how 2.22 is read in as a floating point value.

Andrew,

Thank you very much for your helpful comments. Our MPFR library is 3.1.2. I
applied the cumulative patch on http://www.mpfr.org/mpfr-current/allpatches,
but it did not solve the original problem, unfortunately. How can we identify
this is an inherent limitation or a potential bug of MPFR? Any suggestions
greatly help us.

Ian,

Thank you very much for your helpful clarification. I confirmed that the unit
test passes with both of GC and GCCGO, when we modify the test from:
        assertEquals(t, "2.22 PB", HumanSize(2.22*PB))
to:
        assertEquals(t, "2.22 PB", HumanSize(int64(float64(2.22*PB))))
I will propose this fix to Docker.
