calc: Yanking Into Stack
15.2 Yanking into the Stack
===========================
The ‘C-y’ command yanks the most recently killed text back into the
Calculator. It pushes this value onto the top of the stack regardless
of the cursor position. In general it re-parses the killed text as a
number or formula (or a list of these separated by commas or newlines).
However if the thing being yanked is something that was just killed from
the Calculator itself, its full internal structure is yanked. For
example, if you have set the floating-point display mode to show only
four significant digits, then killing and re-yanking 3.14159 (which
displays as 3.142) will yank the full 3.14159, even though yanking it
into any other buffer would yank the number in its displayed form,
3.142. (Since the default display modes show all objects to their full
precision, this feature normally makes no difference.)
The ‘C-y’ command can be given a prefix, which will interpret the
text being yanked with a different radix. If the text being yanked can
be interpreted as a binary, octal, hexadecimal, or decimal number, then
a prefix of ‘2’, ‘8’, ‘6’ or ‘0’ will have Calc interpret the yanked
text as a number in the appropriate base. For example, if ‘111’ has
just been killed and is yanked into Calc with a command of ‘C-2 C-y’,
then the number ‘7’ will be put on the stack. If you use the plain
prefix ‘C-u’, then you will be prompted for a base to use, which can be
any integer from 2 to 36. If Calc doesn’t allow the text being yanked
to be read in a different base (such as if the text is an algebraic
expression), then the prefix will have no effect.
