What is this test supposed to do?

----
    int exp;
    real mantissa = frexp(123.456, exp);
    assert(equals(mantissa * pow(2.0L, cast(real)exp), 123.456, 19));
----
equals: x = 67.456
equals: y = 123.456
equals: ndigits = 19
bufx = '67.45600000000000307'
bufy = '123.4560000000000031'
core.exception.AssertError at testmath.d(170): Assertion failure
