.S_FLOATING evaluates the specified floating-point constants and
    stores the results in the object module. .S_FLOATING generates
    32-bit, single-precision, floating-point data (1 bit of sign, 8
    bits of exponent, and 23 bits of fractional significance). See
    the description of .T_FLOATING for information on storing double-
    precision floating-point IEEE numbers and the descriptions of
    .D_FLOATING, .F_FLOATING, and .G_FLOATING for descriptions of
    other floating-point numbers.
