EngineeringForm[expr, n]
prints with numbers given to n-digit precision.
  • In "engineering notation" the exponent is always arranged to be a multiple of 3.
  • The following options can be given:
DigitBlockInfinitynumber of digits between breaks
ExponentFunctionAutomaticfunction to apply to exponents
ExponentStep3steps by which exponents can increase
NumberFormatAutomaticfunction used to assemble mantissa, base, and exponent
NumberMultiplier"×"string to use to indicate multiplication
NumberPadding{"",""}strings to use for left and right padding
NumberPoint"."decimal point string
NumberSeparator{",", " "}string to insert at breaks between blocks
NumberSigns{"-",""}strings to use for signs of negative and positive numbers
