This is done so that the numbers can match units as defined by the International System of Units (SI). The engineering notation is the same as the scientific notation, but the exponent is restricted to multiples of 3, resulting in larger values for the significand m - between 1 and 1,000, instead of 1 and 10. You need to use the exponent notation when using our scientific notation calculator mode, since it is not convenient to enter numbers in the classic ' x 10 n' form, due to the exponent requiring a separate field to be filled. E-notationĬalculators and commonly used programming languages like Java, Python, JavaScript, PHP, C++ use the E-notation (exponential notation) to display numbers too large for their display or the allocated space on a monitor. It is hard to compare the two this way, but when we write them as 1.6726 x 10 -24 and 9.109 383 56 x 10 -28 we can just compare the exponents, and since -24 is larger than -28, the proton is about 4 orders of magnitude (10,000 times) more massive than the electron. 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.
