If you convert a decimal number containing decimal places to another number system, Calculator shortens the number to its integer.

Numbers converted from hexadecimal, octal, or binary to decimal appear as integers.


Four number systems are available: decimal, hexadecimal, octal, and binary.


Four operators can be used in standard calculations:

/	divide

*	multiply

-	subtract

+	add
