Supposing that both the base and result sizes were both full size 64-bit

inflating 64 bytes is way overkill.  Limit it to 20 bytes instead which
should be plenty enough for a couple years to come.

2^63 ~ 9.2e18

Thus one signed 64-bit number can take up 1 sign + 19 digits + 1 nul.
That's 21 bytes.

If you don't like the constant, 4*sizeof(integer type) should work.
(Assuming sizeof measures in bytes.)
