hex2fp

Convert IEEE hexadecimal string to single or double precision numbers

HEX2FP is a modified version of the Mathworks HEX2NUM.

It converts hexadecimal representations of floating point numbers:

• 8 character IEEE hexadecimal strings are converted to single precision numbers
• 16 character IEEE hexadecimal strings are converted to double precision numbers

It is ALMOST compatible with HEX2num:

• hex2fp('400921fb54442d18') returns pi.
• hex2fp('bff') returns single(-1.875) but hex2num('bff') returns -1.
• hex2fp('40490fdb') returns single(pi)
• hex2fp('bf8') returns single(-1).
• hex2fp('bff ') with more than 5 spaces returns -1.

There are other versions that handle single precision numbers but I needed maximum compatibility with hex2num and automatic switching between singles and doubles.
