A number expressed by the significant figures times a base raised to a power. Thus 139 000 might be written as 1.390×105 to indicate four significant figures. Writing numbers in floating-point format prevents the loss of significant figures in case the number becomes too small or too large for a fixed register. Computers usually use bases that are a power of 2 rather than the base 10.
