-- This file tests base conversions from string to a decimal number
-- and back to a string (in either Scientific or Engineering form)

-- Note that unlike other operations the operand is subject to rounding
-- to conform to emax and precision settings (that is, numbers will
-- conform to rules and exponent will be in permitted range).
