     90 * Partition capacity represents both value and precision.
     91 * It is a decimal floating point value combined with a decimal
     92 * capacity unit. There is an integer mantisa @c m which in combination
     93 * with the number of decimal positions @c dp gives a decimal floating-point
     94 * number. E.g. for m = 1025 and dp = 2 the number is 10.25. If the unit
     95 * cunit = cu_kbyte, the capacity is 10.25 kByte, i.e. 10 250 bytes.

     98 * precise.
