This question already has an answer here:
My impression is definitely not but perhaps there is a clever trick? Thanks.
Not directly, but there are 64 bit arithmetic operations which can be easily combined to perform 128 bit (or greater) precision.
The xmm registers can do arithmetics on 8, 16, 32 and 64 bit integers. It doesn't produce a carry flag so you can't extend the precision beyond 64 bits. The extended precision math libraries use the general purpose registers which are 32 bit or 64 bit, depending on the OS.
