What is the collective name for the digits before and after decimal point?

• Integer and fractional parts. – user Apr 11 at 23:18
• I have heard of both "integer part" as well as "integral part" for the part to the left of the decimal point. – Andrew Chin Apr 11 at 23:22

The part before the decimal point, the whole number $$120$$ in your example, is often referred to as the Characteristic and can be seen here https://mathworld.wolfram.com/Characteristic.html. The part after the decimal point, the fractional part $$590$$ in your example, can be referred to as the Mantissa. More information on this can be found here https://mathworld.wolfram.com/Mantissa.html.
• In this example, all of $120.590$ are significant figures, but that is not how the different parts of this number are called. The question is asking about the names of the different collections of digits. – swolo Apr 11 at 23:17
