To customise the format of numbers with sc:
      1. You can change the field-width and precision of entire columns
	(only) using the inbuilt format-changer, the 'f' command.
	This still leaves you in fixed-point notation which may not be what
	you want.
      2. Print the particular cell as a STRING, and use the @fmt()
	function to convert a numeric expression into the displayed string.
	(To get this to work, type back over the leading '"' that sc gives
	you when you issue the '<' or '>' command.)
      3. I wanted sc to revert to exponential notation whenever:
		- a value printed as "0" but was non-zero (ie abs(x)>1e-37)
		- a value overflowed the column width.
	I patched the source code to do this, can send the patch if you like.
