What does it mean if there is a comma in a number like this?
$�1,02
It could mean anything, but usually, the comma should have been a decimal point.
Many countries in Europe (and maybe elsewhere) interchange the comma and decimal point:
$1,25 or 32.352.100
When a comma is used in a number, it typically acts as a thousands separator or a decimal point, depending on the context. In the case of the number $1,02, the comma is being used as a decimal separator.
To understand the exact meaning of the comma in this number, it is important to consider the currency used and the customary formatting rules in that region. In many countries, such as the United States, the comma is used as a thousands separator, while the decimal point is represented by a period. However, in some other countries, such as European countries, the comma is used as the decimal separator, and the period is used as the thousands separator.
Since the symbol $ is often associated with the United States currency, it is likely that the comma in the number $1,02 is functioning as a decimal separator. In the US, this number would typically be interpreted as one dollar and two cents.
To confirm the meaning of the comma in a specific context, it is best to consult the local conventions or ask for clarification from the source of the number.
