That is kind of what it does.

FIX n shows n digits to the right of the decimal point.

SCI n shows n digits to the right of the decimal point in the mantissa part.

ENG n does the same thing as SCI n but adds zeroes as needed while adjusting the exponent to be a multiple of 3.

178 in SCI 0 would be: 2. 02

To get that in ENG 0 and have a mantissa between 1 and 1000 (excluded) you need to take 2 off the exponent and insert 2 zeroes before the decimal: 200. 00
