VMS Help MACRO, VAX MACRO Assembler, Directives, .F FLOATING (.FLOAT)  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Evaluates the  specified  floating-point  constants  and  stores
    the results   in   the  object  module.   .F_FLOATING  generates
    32-bit, single-precision, floating-point data (1  bit  of  sign,  8
    bits  of exponent, and 23 bits of fractional significance).

    literal-list

    A list of floating-point constants.  The constants cannot contain
    any unary  or  binary  operators  except unary plus and unary
    minus.  The floating-point constants in the literal list must not
    be preceded  by the floating-point unary operator (^F).
