Numbers in a scientific notation allow for easier comparison of orders-of-magnitude. The sign of the number is written the usual way. The most convenient form, called a normalized notation, is one in which the exponent is chosen in such a way that the coefficient is between 1 and 9. The exponent n is always an integer (whole number) while the coefficient m (mantissa, significand) can be any real number. The form of a number in scientific notation is m x 10 n - m times 10 raised to the power of n. Even with the improvement of computing power, the scientific notation remains popular among engineers, scientists and mathematicians, who, alongside students, are the primary users of this scientific notation calculator / converter. On many calculators it is designated as the "SCI" mode. The scientific notation is also called E-notation, scientific form of a number, standard index form, or just standard form, is a way of writing numbers deemed too big or too small to be conveniently used in their decimal form.
