Create a new numeric type represented by Scientific. Use it for JSON (#168).

Possible conversions:

  • Integer <: Scientific: safe, but might conflict with Scientific <: Literal.
  • Scientific <: Rational (exact): unsafe, e.g. 1E1000000000.
  • Scientific <: Number (inexact): safe, ugly, not injective, would have to special-case Integer.
  • inexact: Scientific -> Number: safe
  • dynamic Rational -> Maybe Scientific: safe

Should literals be of type Scientific?

Should Scientific exponent be limited? If so, how? Note max Double value is 1.7976931348623157E308.

Representation as Literal: would be as large rational.
