...FLoating point can engender some interesting representations. Consider the exponent

0000 0000 0000 0001 octal = 1 exactly.
EL-X8 doesn't use the bias, so the floating point representation of an integer under
2^39 is the same as the integer representation. And the rule for normalizing float values
preserves that (normalization makes the exponent as close to zero as possible -- rather
different than the usual rule).
