I’m trying to do to number with my code width matematic

Example:

print(tonumber("1 + 1")) -- Gives You Nil

i ended my place!: Code.rbxl (23.4 KB)

say !Calculate and (number1) (calculation) (number2)

#2

Could you give us more detail? Like an error in the output?

#3

it does not give me errors, it only returns null

#4

You are using tonumber(), which converts string into numbers, but that only works if you have given those strings a set number.

Here’s a guide:

You can easily convert a string to a number by using the tonumber() function. This function takes one argument (the string) and returns it as a number. If the string doesn’t resemble a number, for example "Hello" , the tonumber() function will return nil .

i can’t.

Yes or Yes I have to use strings because I’m doing something that only uses strings

#6

Does it resemble a number? If the string does not resemble a number it will return nil.

#7

so what solution is there for my case?

#8

Oh wait you posted the article I just read. Rip.

#10

this does not work for me I have to do this with divided strings I need strings together

#11

if this worked then string calculators would be easier, anyways you could do

print(tonumber("1") + tonumber("1"))

that would print out 2
anyways yea since “1 + 1” can’t be turned into a number it outputs nil

#12 
Local math = “1 + 1” 

print(tonumber(math))

This might work but I don’t know I’m not a pro scripter.

#13

yea that wouldn’t work sorry
“1 + 1” would print out nil because you can’t turn that into a number

also Print() isn’t a thing

#14

Oh ok. I’m not a good scripter so I would not know.

#15

that does not work is the same

local var = "1 + 1"

print(tonumber(var))

=

print(tonumber("1 + 1"))

#16

when will they answer me???

#17

Hang in there. I’m working on finding a solution right now.

#18

Try this

local var = “1” + “1”

print(tonumber(var))
#19

wait one second I already said this

#20

are you only doing math related things?
do you want a string calculator?

#21

I’m not very good at string manipulation. There are many ways to go about this, but this is just my simple way at achieving what you want.

local test = "5 + 5"

local operations = {
	["+"] = function(a, b)
		return a + b
	end,
	
	["-"] = function(a, b)
		return a - b
	end,
	
	["*"] = function(a, b)
		return a * b
	end,
	
	["/"] = function(a, b)
		return a / b
	end,
}


local values = string.split(test, " ")

local x = values[1]
local oper = values[2]
local y = values[3]

print(operations[oper](x, y))
