在Roblox Studio中,我们可以使用math库和字符串格式化函数string.format进行数字舍入。需要注意的是,由于Roblox Studio使用的是Lua 5.1版本,因此不支持Lua5.3版本中新增的math.round函数。在使用string.format时,需要将数字先转换为字符串,然后再使用tonumber函数将其转换回数字类型。
To convert a string to a number, use the tonumber() function. If the string doesn't have a number representation, tonumber() returns nil.local numericString = "123" print(tonumber(numericString)) --> 123 local alphanumericString = "Hello123" ...
Luau coerces strings to numbers inarithmetic operations. This behavior is built into Luau. If the types are incompatible for arithmetic, Luau throws an error and doesn't run the rest of the script. For example, you can't add a string to a number if the string does not represent a numbe...

First, it generates a seed that’s random from 100000 to 999999, then make a variable that turns the seed into a string in order to reverse the seed then turn it back to a number to do a calculation like this: RevSeed - GenSeed ...
b=1print(typeof(b))--number b='123'print(typeof(b))--string 上面的代码在Roblox中当然是可以的,但是在Roblox中写程序的时候,最好是使用local关键字来初始化变量。如果没使用local的话,会在整个脚本的范围定义变量,大多数情况下是没有必要的,这也是一个不好的编程风格。
