bits in @var{integer1} to the left @var{count} places, or to the right
if @var{count} is negative, bringing zeros into the vacated bits. If
@var{count} is negative, @code{lsh} shifts zeros into the leftmost
-(most-significant) bit, producing a positive result even if

@var{integer1} is negative. Contrast this with @code{ash}, below.
Here are two examples of @code{lsh}, shifting a pattern of bits one
@defun expt x y
This function returns @var{x} raised to power @var{y}. If both
-arguments are integers and @var{y} is positive, the result is an
+arguments are integers and @var{y} is nonnegative, the result is an
integer; in this case, overflow causes truncation, so watch out.
If @var{x} is a finite negative number and @var{y} is a finite
non-integer, @code{expt} returns a NaN.
After the @samp{%} and any field number, you can put certain
@dfn{flag characters}.
- The flag @samp{+} inserts a plus sign before a positive number, so
+ The flag @samp{+} inserts a plus sign before a nonnegative number, so
that it always has a sign. A space character as flag inserts a space
-before a positive number. (Otherwise, positive numbers start with the
-first digit.) These flags are useful for ensuring that positive
-numbers and negative numbers use the same number of columns. They are
+before a nonnegative number. (Otherwise, nonnegative numbers start with the
+first digit.) These flags are useful for ensuring that nonnegative
+and negative numbers use the same number of columns. They are
ignored except for @samp{%d}, @samp{%e}, @samp{%f}, @samp{%g}, and if
both flags are used, @samp{+} takes precedence.
contain either numbered or unnumbered %-sequences but not both, except
that %% can be mixed with numbered %-sequences.
-The + flag character inserts a + before any positive number, while a
-space inserts a space before any positive number; these flags only
+The + flag character inserts a + before any nonnegative number, while a
+space inserts a space before any nonnegative number; these flags only
affect %d, %e, %f, and %g sequences, and the + flag takes precedence.
The - and 0 flags affect the width specifier, as described below.
