scientific notation uses 1 <= absolute value of coefficient < 10
How?
How this is calculated
The parser keeps the typed digits and decimal position as strings. For a nonzero number, it finds the first nonzero digit, shifts the decimal point to make the coefficient at least 1 and less than 10, and records the shift as the exponent.
Engineering notation uses an exponent that is a multiple of 3. Zero is displayed by convention because any exponent multiplied by zero still gives zero.
Formula: scientific notation uses 1 <= absolute value of coefficient < 10
