in reply to Float/double to hex?

1 / 7 = 0.142857142857143 = 0x6FDF1234

That hex value doesn't correspond to either a float or double in IEEE format?

print unpack 'h*', pack 'f', 1/7;; 529421e3 print unpack 'h*', pack 'd', 1/7;; 2942942942942cf3

      I've no idea what that hex value is, but it certainly isn't any IEEE representation of 1/7.
