2. UA type conversion:
1) Lua also has hermit conversion (automatic) and display conversion (forced). The conversion rules are as follows:
A) implicit conversion: if you do arithmetic operation on the "number" string, Lua will automatically convert the number string to an integer, and then perform the operation. However, if the string contains other non numeric characters (except the white space on both sides), a conversion error will occur, and Lua will not automatically convert char to its ASCII value. That's the problem you have
If a numeric value is used for string operations, such as concatenation, the number will also be automatically converted to a string
b) explicit conversion: the built-in functions toString and ToNumber are used to convert numbers and strings respectively. Similarly, if there are non numeric characters in the string, the ToNumber will convert to report an error.

Lua data conversion problem:

all data types in Lua will be internally converted to double type. If you need to display a double type, you can do this:

Lua:

local num = 3.14

printf(totring num)

when Lua executes redis command through call or pcall function, the return value of the command will be converted into Lua data structure. Similarly, when Lua script runs in the built-in interpreter of redis, the return value of lua script will be converted into redis protocol, and then Eval will return the value to the client

the conversion between data types follows such a design principle: if a redis value is converted to a Lua value, and then the converted Lua value is converted back to a redis value, then the redis value obtained from this conversion should be the same as the original redis value

in other words, there is a one-to-one conversion relationship between Lua type and redis type

There is no difference between integer and floating point in

Lua. Therefore, we always convert Lua's number to the reply of an integer, which will round off the decimal part. If you want to return a floating-point number from Lua, you should treat it as a string (see, for example, the zscore command)

There is no simple way to have Nils inside Lua arrays, this is a result of lua table semantics, so when redis converts a Lua array into redis protocol the conversion is stopped if Anil is accounted.

Lua is a dynamically typed language, so variables have no type, only values have type. Values can be stored in variables, passed as parameters, and returned as results

in Lua, although there is no data type of variable, there is a value of type

6. Upstairs nonsense, the record is generally not charged. You need to bring the filing application, unit introction letter, power of attorney, ID card, and then the company's business license, tax organization safety proction certificate, as well as the certificate of key personnel, as well as the certificate of no bad record, no arrears of migrant workers' wages.

7. In the early stage, although the ingot is not as expensive as the ore, it saves a lot of time. When you get to 245 or so, you will spend 300-400 cards (selling ah ingots) to save a lot of time. After 245, you can go to xilisus to collect secret silver. Now the price is very high, and you can make a big profit. Then 300 people go to Outland to ride big birds one by one, and no one will pick it. 375 to the North Pole
