2nd para

In the description of $myDouble, the stated value 9 in parentheses, i.e. "(53-bit, 9 bits of precision)", is probably wrong.

$myArray[-1..2]

The description, "PowerShell wraps around because the first number in the range is positive, and the second number in the range is negative", does not match up with the example.

-shl and -shr entries

Both of these are wrong in the description:

-shl Binary shift left:
$value -slh $count

should be:
$value -shl $count



-shr Binary shift right:
$value -slr $count

should be:
$value -shr $count

End of Table 1-8

Table 1-8 lists "other" operators. The invoke/call operator, &, is missing from this table and from the index. It is listed on page 53 under the topic "Running Commands", but I believe it should be in the table of operators as well as the symbol section of the index. Actually, I guess the dot operator described on page 54 should also be in the table of operators. This operator is located in the index.

switch options ( expression )

foreach Statement

In the line
:loop_label foreach (variable in expression)
the word "in" should be in regular roman (not italic) font.

8th row

"Dismount" is listed as a synonym for "dismount". "Unmount" would be useful here, and may have been what was intended.
