''Decimal is a number in the decimal system'';wordreference says but i didn't anything.Can that be saying such as 1,2 , 000,5 or 55,2
Just to be clear, there is a difference between a decimal indicator and a decimal number.
A decimal
number is any number in a system to the base 10.
A decimal
indicator is the symbol or expression used to denote a decimal fraction.
Some countries use the ',' as the decimal indicator while others use the '.'
International air controllers speak the word "decimal" to avoid confusion, for example: "Contact ground control now on one twenty-one decimal nine."
