Is there a word that describes the separation of dollars and cents?

Take the following amount:

$ 12.54

I am looking for a term that describes the separation of dollars and cents. Of course there is a term that describes the character that does the job which most people would call decimal or period.

Another example:

John, Adams, Male

This is a small comma-separated list of values. In this case, a comma separates the values "John", "Adams", and "Male". The comma is also called a delimiter.

Is there a term that describes the decimal point as a separator?
Is it a separator?

Answer

In general terms, the radix point separates the integer part of a number from its fractional part. In base 10, the radix point is more commonly called the decimal point.
