\begin{funcdesc}{frexp}{x}
Convert a floating-point number to fractional and integral
components. If \var{x} is zero, returns \code{(0.0, 0)}, otherwise
returns \code{(\var{frac}, \var{exp})} such that \code{\var{frac} *
2**\var{exp}} will equal \var{x}. \var{exp} will be an integer, and
the absolute value of \var{frac} will be in the range [0.5, 1.0)
(\var{frac} will share the sign of \var{x}).
% Blessed by Tim.
Return the mantissa and exponent of \var{x} as the pair
\code{(\var{m}, \var{e})}. \var{m} is a float and \var{e} is an
integer such that \code{\var{x} == \var{m} * 2**\var{e}}.
If \var{x} is zero, returns \code{(0.0, 0)}, otherwise
\code{0.5 <= abs(\var{m}) < 1}.
