(SPARC only) A quadruple-precision constant is a basic real constant or an integer constant, such that it is followed by a quadruple-precision exponent. See "Real Constants". @
A quadruple-precision exponent consists of the letter Q, followed by an optional plus or minus sign, followed by an integer.
A quadruple-precision constant can be positive, negative, or zero. If no sign is present, the constant is assumed to be nonnegative.

The form and interpretation are the same as for a real constant, except that a Q is used instead of an E.
The restrictions are:
Other than the optional plus or minus sign, a decimal point, the digits 0 through 9, a blank, and the letter Q. No other characters are allowed.
The magnitude of an IEEE normalized quadruple-precision floating-point value must be in the approximate range (3.362Q-4932, 1.20Q+4932).

Each such datum is aligned on 8-byte boundaries.
