Scientific notation writes a number as a mantissa multiplied by a power of ten.
12345 becomes 1.2345 x 10^4 in scientific notation and 12.3450 x 10^3 in engineering notation.
Engineering notation uses an exponent that is a multiple of 3.
Yes. It preserves the sign while formatting the mantissa and exponent.
Zero is rejected here because scientific notation requires a nonzero value.
The calculator shows four decimal places in the formatted results.
