Hey!

so far I've only seen calculators script which can handle only 2 numbers!
But now you can calculate with multiple numbers.

Function in this include takes string and returning result as integer..
(soon as Float)

For now it works only with:

Код:

Addition 		(+)
Subtraction 		(−)
Multiplication 		(Ч)
Division 		(ч)

Function

Код:

TryCalculate(compute[], &result, &bool:fail, failstring[], const len = sizeof(failstring));

compute[] - String which will be calculated
&result - Return result in this variable
&bool:fail - Return 'true' if is there any errors
failstring[] - Store error string
const len = sizeof(failstring)


From example:

will return




But this:

Script will remove empty letters and return:





return error:





=





=

(real calculator)




Example

Код:

CMD:calculate(playerid, arg[])
{
	new 
		compute[64], 
		result, 
		bool:fail, 
		error[24],
		str[64]
	;
	if (!sscanf(arg, "s[64]", compute))
	{
		TryCalculate(compute, result, fail, error, sizeof(error));
		if(!fail)
		{
			format (str, sizeof(str), "Calculated: %d", result);
			SendClientMessage(playerid, -1, str);
		}
		else
		{
			format (str, sizeof(str), "Calculate Error: %s", error);
			SendClientMessage(playerid, -1, str);
		}
	}
	else SendClientMessage(playerid, -1, "Usage: /calculate [anything]");
	return 1;
}

Useful for the laziest scripter!

Yep
(from real calculator)

You guys should rely more on your math skills, not a piece of software.

I'll just leave this link here:

5*5-1/2=24,5
25-0,5=24,5

Operation sequence.

Yea true, but i didn't made () support yet, and logical calculate, but it work exactly like pc calculator

It's accurate only for PC calculator.

Still not correct.
MS calculator does the math at the time you press a sign button (+, -, *, /), but when you write down an entire expression (as in your screenshots), it must be calculated according to the operations order.

There are multiple modes. The default one is a really shitty version.
Click on "View" and check the other modes.

Operation order:

1. ()
2. * and /
3. + and -

[Ivan_Ino]

still working on that

exponents and roots have higher priority than * and / i think.

A suggestion you can add sin,cos,tan and logarithm operations too and if you can add integral and differential operations that would be pretty awesome too .
