8.2. Numerical Constants

1、Example 8-4. Representation of numerical constants

同C语言一样，字符也是整数。但是@和_代表是多少不知道？而且把它们转化为十进制的方法忘记了。

  32 let "b64 = 64#@_"

  33 echo "base-64 number = $b64"             # 4031

  34 # This notation only works for a limited range (2 - 64) of ASCII characters  35 # 10 digits + 26 lowercase characters + 26 uppercase characters + @ + _

  36

  37

  38 echo

  39

  40 echo $((36#zz)) $((2#10101010)) $((16#AF16)) $((53#1aA))

  41                                          # 1295 170 44822 3375

英语疑难: evaluates

A number with an embedded # evaluates as BASE#NUMBER (with range and notational restrictions).
