Negative Numbers - HP -32S Owner's Manual

When a number appears in hexadecimal, octal, or binary base, it is
shown as a right-justified integer with up to 36 bits (12 octal digits or
9 hexadecimal digits). Leading zeros are not displayed, but they are
important because they indicate a positive number. For example, the
binary representation of 12510 is displayed as:
1111101
which is the same as these 36 digits:
000000000000000000000000000001111101
Negative Numbers
The leftmost (most significant or 'highest') bit of a number's binary
representation is the sign bit; it is set (1) for negative numbers. If there
are (undisplayed) leading zeros, then the sign bit is 0 (positive). A
negative number is the 2's complement of its positive binary number.
