			-- to negative or positive infinity
			--
			-- Parameters:
			--   d: A double-precision floating point number.
			--
			-- Returns:
			--   true if d evaluates to System.Double.PositiveInfinity or
			--   System.Double.NegativeInfinity; otherwise, false.

			-- Returns a value indicating whether the specified number evaluates
			-- to positive infinity.
			--

			-- to negative infinity.
			--
			-- Parameters:
			--   d: A double-precision floating point number.
			--
			-- Returns:
			--   true if d evaluates to System.Double.NegativeInfinity; otherwise,

			-- (Static)
			-- Returns a value indicating whether the specified number evaluates
			-- to a value that is not a number (System.Double.NaN).
			-- Parameters:
			--   d: A double-precision floating point number.
			--
			-- Returns:

feature -- Conversion

	frozen from_string_attempt (s: SYSTEM_STRING; style: NUMBER_STYLES; provider: IFORMAT_PROVIDER; result_: TYPED_POINTER [REAL_64]): BOOLEAN
			-- (Static)
			-- Converts the string representation of a number in a specified style
			-- and culture-specific format to its double-precision floating point
			-- number equivalent.
			--
			-- Parameters:
			--   s: A string containing a numberto convert.
			--   style: The combination of one or more
			--     System.Globalization.NumberStylesconstants that indicate the
			--     permitted format of s.
			--  provider: An System.IFormatProvider that supplies culture-specific
			--    formatting information about s.
			--  result_: A double-precision floating-point number equivalent to the
			--    numeric value or symbol specified in s. If the return value is
			--    false, result_ is set to zero.
			--
			-- Returns:
			--   true if s is converted successfully; otherwise, false.

			-- Converts the string representation of a number to its double-precision
			-- floating point number equivalent.
			--
			-- Parameters:
			--   s: A string containing a number to convert.
			--
			-- Returns:
			--   A double-precision floating point number equivalent to the numeric
