f = hex2num('string')
hex2num('string') converts the hex value in string string to the IEEE double precision floating-point number it represents. NaN, Inf, and denormalized numbers are all handled correctly. Fewer than 16 characters are padded on the right with zeros.
f =hex2num('400921fb54442d18')f =3.14159265358979
hex2num only works for IEEE numbers; it does not work for the floating-point representation of the VAX or other non-IEEE computers.
