4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync/* 11-bit exponent (VAX G floating point) is 308 decimal digits */

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * MAXEXPDIG is the maximum number of decimal digits needed to store a
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * floating point exponent in the largest supported format. It should
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * be ceil(log10(LDBL_MAX_10_EXP)) or, if hexadecimal floating point
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * conversions are supported, ceil(log10(LDBL_MAX_EXP)). But since it
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * is presently never greater than 5 in practice, we fudge it.
