Number displays incorrectly if the first digit is zero

[icekiller8002]

This is my code:

Code: Select all

function love.load()
     text = "A random 10 digit number (i.e. 5642452501)"
     yours = tonumber(text)
     new = tostring(yours)
     text = "("..new:sub(1,3)..") "..new:sub(4,6).."-"..new:sub(7,10)
end

function love.draw()
     love.graphics.print(text,0,15)
end

Normally, if the first digit is not 0, it will look like this:
(564) 245-2501

However, if the 1st digit is 0, it just gets ignored. Let's say my generated number was 0642452501 instead. It would display as this:
(642) 452-501

As you can see, the number is only 9 digits. And if my number is all zeroes, it looks like this:
(0) -

How can I make it so any 1st digits of zero are not ignored? I'm struggling to find out how I can fix this. Any help would be appreciated.

That sounds like a case of insignificant digits.
Zeroes that precede a number are irrelevant because 00003 is still 3.
You need to ensure the text you're printing is a string, not a number.
Just wrap it in tostring() like so:

Code: Select all

function love.draw()
	love.graphics.print(tostring(text), 0, 15)
end

If you want to be sure it's a valid number but don't want to strip leading zeros you can use string.format:

Code: Select all

str = string.format("%010d", tonumber(text))

Converting a string to a number will remove any leading 0's, maybe you can filter out any non-numeric characters instead?

Code: Select all

local text = "My number is 06-12344566"
print(text) -- Output: "My number is 06-12344566"
text = string.gsub(text, "%D", "")
print(text) -- Output: 0612344566

The gsub function let's you replace characters in a string, %d refers to numeric characters (0-9), and if you change it to a capital letter (%D) it inverts, making it refer to non-numeric characters.

Keep in mind, I want the number to display as (XXX) XXX-XXXX, not XXXXXXXXXX

Code: Select all

-- in love.load
local one, two, three = love.math.random(0,999), love.math.random(0,999), love.math.random(0,9999)
text = ('(%03d) %03d-%04d'):format(one,two,three)

-- in love.draw
love.graphics.print(text, 0, 0)

It would work with one number as well, but you'd need to math out the divisions and remainders.

You already have the code to print it properly.

This is my code:

Code: Select all

[...]
     text = "("..new:sub(1,3)..") "..new:sub(4,6).."-"..new:sub(7,10)
[...]

Just replace 'new' with the tostring().

Code: Select all

phoneNumber = tostring(text)
printedText = "(" .. phoneNumber:sub(1, 3) .. ") " .. phoneNumber:sub(4,6) .. "-" .. phoneNumber:sub(7,10)

Just replace 'new' with the tostring().

Code: Select all

phoneNumber = tostring(text)
printedText = "(" .. phoneNumber:sub(1, 3) .. ") " .. phoneNumber:sub(4,6) .. "-" .. phoneNumber:sub(7,10)

Code: Select all

return tostring(0123456789)
--> "123456789"
return tostring(0000000000)
--> "0"

As Nixola and i have said above, at least do this:

Code: Select all

phoneNumber = ('%010d'):format(text)
printedText = "(" .. phoneNumber:sub(1, 3) .. ") " .. phoneNumber:sub(4,6) .. "-" .. phoneNumber:sub(7,10)

^ ^ ^THIS BE WORKING^ ^ ^
Just a bit of an eye-catcher since people are seemingly hard of sight.

phoneNumber = tostring(text)
printedText = "(" .. phoneNumber:sub(1, 3) .. ") " .. phoneNumber:sub(4,6) .. "-" .. phoneNumber:sub(7,10)

So actually instead of

Code: Select all

     new = tostring(yours)
     text = "("..new:sub(1,3)..") "..new:sub(4,6).."-"..new:sub(7,10)

he should write

Code: Select all

phoneNumber = tostring(text)
printedText = "(" .. phoneNumber:sub(1, 3) .. ") " .. phoneNumber:sub(4,6) .. "-" .. phoneNumber:sub(7,10)

Wow that makes an big difference.
Ok, its make a big difference. Converting a random 10 digit number in text form to an actual number is ok. Converting an phone number to non text form is actual hazard source. Because some number would become:
(000) 000 0911

Am i blocked by everyone or are you guys just deliberately ignoring the actually working solution that was already posted, by choice?
sheesh, i'm not as bad as raidho...
