In
mathematics and
computing, a
radix point (or
radix character) is the symbol used in numerical representations to separate the
integer part of a number (to the left of the radix point) from its
fractional part (to the right of the radix point). "Radix point" is a general term that applies to all
number bases. In
base 10 notation, the radix point is more commonly called the
decimal point, where the prefix implies base 10. Similarly, the term "binary point" is used for
base 2.
