NumberFormat

NumberFormat
is an option for NumberForm and related functions that specifies how the mantissa, base, and exponent should be assembled into a final print form.
  • With the setting NumberFormat->f, the function f is supplied with three arguments: the mantissa, base and exponent of each number to be printed. »
  • The arguments are all given as strings. »
  • When no exponent is to be printed, the third argument is given as . »
  • The function f must return the final format for the number.
