String to float conversion needed

[Jonathan Shapiro]

[Aren't you hungry...?]

	This request should be easy.  None of the sites I have access to have
the IEEE floating point stuff. I am in need of a function/procedure, in C,
to convert a real number string to a real number.  The catch is, this is
not for the VAX, so scanf won't work.  The target formats I am looking for
are:

Single Precision:

       Sign bit (1)|Biased Exponent(8)|Mantissa Magnitude(23)

       Biased exponent = true exponent + 127

Double Precision:

       Sign bit (1)|Biased Exponent(11)|Mantissa Magnitude(52)

       Biased exponent = true exponent + 1023

	Ideally, these routines should not be dependent on any uniquely VAXish
tricks, though beggars can't be choosers.

Any help that you might provide would be greatly appreciated.

Thank you.
