IMHO it would be nice to see it used in larger-integer-presenting domains: with some limitations, accounting; interpreters where you want 0.1 + 0.2 == 0.3; anywhere there are measurements with units, and factor-of-ten scaling of finite digits is helpful; anywhere you want the simplicity of a single number-type and number-builder; possibly where you want to reserve some exponents for giving language keywords orthogonal number representations.
