Getting length of an integer? - jameskmonger - 11.07.2011

How can I get the length of an integer? I am trying to make a system to generate a random 7 digit phone number, and I am planning to use something like this:

pawn Код:

new randnum;
while (intlen(randnum) != 7) {
       randnum = random(9999999);
}
PlayerData[playerid][PhoneNumber] = randnum;

But I can't find a function to calculate the length of the value though.

(My while loop could be wrong, too, it is meant to keep generating random numbers until it hits a 9 digit one, and then set the player's phone number to that - am I doing it right?)

If I understood good, you want to make random phone numbers starting with 1000000 to 9999999? If yes
num=1000000+random(9000000); EXPLANATION: min_num =1000000+0, max_num = 1000000+9999999=9999999

Yes, I have adapted to that method - I still want to know if there is a function to do what I have asked.

by default - no. You would need to create a custom function for that.

PHP код:



new randnum;

Rand: 

    randnum = random(9999999);

    if(randnum < 10000000) { goto Rand; }

PlayerData[playerid][PhoneNumber] = randnum;

Or:

PHP код:



new randnum, str[8];

Rand: 

    randnum = random(9999999);

    format(str, sizeof str, "%d", randnum);

    if(strlen(str) != 7) { goto Rand; }

PlayerData[playerid][PhoneNumber] = randnum;

pawn Код:

new randnum, str[8]; 
Rand:  
    randnum = random(9999999); 
    format(str, sizeof str, "%d", randnum); 
    if(strlen(str) != 7) { goto Rand; } 
PlayerData[playerid][PhoneNumber] = strval(randnum);

Thanks, strval added to remove tag mismatch warnings.

You can

pawn Код:

while(randnum < 1000000)

You don't need all of that to generate a random 7 digit "phone" number.

EDIT: Then just use strval to make an integer.

Should not be so?

PHP код:



while(randnum > 1000000)

You can use more than and less than operators. You should completely refrain from using 'goto' statements anywhere in your code (there's actually quite a valid reason, other than the dinosaur).
