Dimitris,
 
Answered already.

Numbers are in IEEE single precision (32 
bit) format
(7 significant digits). YYYYMMDD is 8 digits.
 
The 24 bits (including the hidden bit) of mantissa in a 32-bit 
floating-point number represent approximately 7 significant decimal digits. 
Unlike the real number system, which is continuous, a floating-point system has 
gaps between each number. If a number is not exactly representable, then it must 
be approximated by one of the nearest representable values.
