Help converting numbers into pounds and pennies

[Dauntified]

Hello! I’m here looking for help so I can figure out how to convert my numbers into correct GBP format. So far, my code works as it converts long decimals into smaller 2 decimal place numbers.

Here’s my code:

function module.ToDecimalPlace(value)
    value *= 100
    value = math.floor(value)
    value = value / 100
    return value
end

Let’s say “value” in the parameters is 1400.91152

My code will successfully convert this decimal to 2 decimal places.

1400.911.52 ==> 1400.9

The problem being it ends with .9

I need my code to end it with .90 instead to format it correctly as currency.

Any help is appreciated, I don’t think this is a very difficult topic but do let me know if you have any confusions or questions!

I’m not sure I understand the problem. Could you please elaborate?

The returned value is already floored to two decimal places. 1400.91152 rounds to 1400.91. Except if the goal is to also add a zero, for example with 1400.90152 → 1400.90.

In that case, converting to string and formatting can help. Because you’re flooring, it’s the same as getting rid of the rest of the decimals.

local value = 1400.90152
value = string.format("%.2f", value)
print(type(tonumber(value)), value) --> number, 1400.90
