Converting from Decimal to Hex
To convert from decimal to hex, pretend you are making change.
Example To convert \(99_\text{DEC}\) to hex, we first ask how many 16’s it contains. We compute \(6 \cdot 16 = 96\), with remainder 3.
\[ \begin{aligned} 99\,_\text{DEC} &= 6 \cdot 16 + 3 \\ &= \text{0x}63 \\ \end{aligned} \]
Example To convert \(300_\text{DEC}\) to hex, we first ask how many 256’s it contains (one, with remainder 44). Then we ask how many 16’s are contained in 44 (2, with remainder 12).
\[ \begin{aligned} 300\,_\text{DEC} &= 1 \cdot 256 + 2 \cdot 16 + 12 \\ &= \text{0x}12C \\ \end{aligned} \]
