ScientificForm

ScientificForm[expr]
prints with all real numbers in expr given in scientific notation.
ScientificForm
prints with numbers given to n-digit precision.
  • The following options can be given:
DigitBlockInfinitynumber of digits between breaks
ExponentFunctionAutomaticfunction to apply to exponents
ExponentStep1steps 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
SignPaddingFalsewhether to insert padding after the sign
  • ScientificForm acts as a "wrapper", which affects printing, but not evaluation.
