A number, represented by a series of numerals, preceeded by

a space, followed by a power of ten.  Three characters must follow
the "E".  A space may be used instead of a plus sign (+).
The range of a floating point number (one with a decimal point) is
from 9.9999999E+99 to 9.9999999E-99, plus and minus.  The range of
