I was reading about datatypes in ORACLE. I get to known that BINARY_FLOAT, BINARY_DOUBLE use binary precision which make them more efficient than NUMBER as NUMBER use decimal precision.

Please explain about binary precision.

Solution 1

The binary precision is the 'usual' representation of float and doubles in computer memory ("IEEE floating point" at Wikipedia[^]). Machine hardware is optimized for using it.
However, please note, there's a reason why databases provide decimal precision data types (see, for instance, the "decimal32 floating-point format" page at Wikipedia[^]).
