Though power of 2 word sizes look in hindsight like a natural consensus, historical computers used quite a wide variety, including but not limited to 9, 18, 36, 12, 24 and 60 bits.
Power-of-2 computers have tended to end up (leaving aside 8087's 80-bit extended precision) with a choice between 32 and 64-bit floating point formats.
A 12/24 bit computer, when implementing floating point, would naturally tend to 48 bits. Indeed, this precision was actually used in some cases even on power-of-2 computers: https://stackoverflow.com/questions/31928449/what-type-is-this-6-byte-48-bit-number-floating-point-integer
Would 48 bits be enough for most scientific and engineering applications (in a way that 32 is not), or would such a computer need to incur the cost of supporting a higher precision such as 96 bits?
