Usage notes[edit]

When used as a currency symbol, $ precedes the number it qualifies in English, despite being pronounced second. For example, “$1” is read as “one dollar”, not “dollar one” unlike the usage in languages such as French or German: “1 $”, “2,50 $”.

When used for the Portuguese escudo, $ is placed between the escudos & centavos, 2$50. The official symbol for the escudo is (with two bars), but that form is unified with the single-bar form in Unicode. A single-bar dollar sign is frequently employed in its place even for official purposes.
