EngineeringForm

 EngineeringForm[expr]prints with all real numbers in expr given in engineering notation. EngineeringFormprints 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:
 DigitBlock Infinity number of digits between breaks ExponentFunction Automatic function to apply to exponents ExponentStep 3 steps by which exponents can increase NumberFormat Automatic function 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 SignPadding False whether to insert padding after the sign
• EngineeringForm acts as a "wrapper", which affects printing, but not evaluation.
