Number ranges and bits

These may be handy when you loose count. I loose count all the time, so I made this page.

Numbers

The basics.

See: Octal, Hexadecimal and Decimal to hexadecimal table.

Number ranges

Number ranges per hex digit.
The first column shows the number of bits in the 2nd last column.
The last column shows the value divided by 2¹⁰ (k) or 2²⁰ (M).
To improve legibility, hex digits and bits are grouped per four digits.

The next entry in the above table would be the 4G to 64G - 1 range.

Boundaries

The biggest binary - round 32-bit signed positive number:

The biggest 32-bit signed positive number:

The most negative 32-bit signed number:

And the least negative 32-bit signed number:

So 32-bit hex numbers > '7FFF FFFF' may be negative. These are part of the '1000 0000' to 'FFFF FFFF' range.
For 64-bit numbers just double the width: A 64-bit '-1' is '0xFFFFFFFFFFFFFFFF';

Bits

Individual bits and their octal, decimal and hexadecimal values;
For instance, 2⁰ = 1 and 2³¹ = 2147483648 or 0x80000000.
The last column shows the value divided by 2¹⁰ (k), 2²⁰ (M), or 2³⁰ (G).
To improve legibility, hex digits and bits are grouped per four digits.

64-bit

I don't think anyone uses octal or decimal in these ranges.
The 3rd and 6st column show the value divided by 2³⁰ (G), 2⁴⁰ (T), 2⁵⁰ (P) or 2⁶⁰ (E).

The next entry in the above table would be 16 E.
