Avoid -fsanitize=float-cast-overflow

...when converting sal_Int64 9223372036854775807 (i.e., 0xFFFFFFFFFFFFFFF) to
double 9.22337e+18 (i.e., by rounding up to 2^63, represented as
0x43e0000000000000) and then back to sal_Int64 (for which it is now too large).
Started to happen during UITest_writer_dialogs:
