What does 1.905 Round to by decimal?

Answer 1

Oh, dude, 1.905 rounds to 1.91 when you're talking about decimals. It's like when you're at the store and something costs $1.905, they'll probably just charge you $1.91 because they don't want your pocket change cluttering up the place.

Answer 2

Depends what decimal place you wish to round it to. For example, to no decimal places it is 2, to one decimal place it is 1.9, to two decimal places it 1.90 (however it is not entirely necessary to write the zero).
