hexsingle2num converts a single precision IEEE hexadecimal string to a number.

hexsingle2num is a version of hex2num which works with single precision floats. Currently MATLAB hex2num converts to double precision floats.

HEXSINGLE2NUM(S), where S is a 8 character string containing a hexadecimal number, returns a double type number equal to the IEEE single precision floating point number it represents. Fewer than 8 characters are padded on the right with zeros.

If S is a character array, each row is interpreted as a single precision number (and returned as a double).

NaNs, infinities and denorms are handled correctly.

Example:
hexsingle2num('40490fdb') returns Pi.
hexsingle2num('bf8') returns -1.
