Code:

new value;
0.4 * inputtext = value; // ERROR
GivePlayerMoney(playerid, value);

[Kaliber]

Write it like this:

Code:

new value = 0.4 * strval(inputtext); // ERROR
GivePlayerMoney(playerid, value);

hm.. It doesn't work. If i type 6 it shows 12904821094 and give me 1293031 money

Code:

new hh[128], value;
value = strval(inputtext) * 0.4;   <=== TAG MISMATCH
GivePlayerMoney(playerid, value);

Still tag mismatch.

[Threshold]

pawn Code:

new Float:value = strval(inputtext) * 0.4;
    GivePlayerMoney(playerid, floatround(value, floatround_round));

EDIT:

I would also recommend that you set a limit on what a player can enter. To make sure they don't enter negative or very high positive values such as -194581371489144 and 19478189587175 for instance.
Example:

pawn Code:

if(!(1 <= strval(inputtext) <= 999999999)) return SendClientMessage(playerid, -1, "You must put a value between 1 and 999999999.");

I've already have limit:

Code:

if(strval(inputtext) >= 100 || strval(inputtext) <= 700)

Yep. Now i fixed it and working. Thanks again REP++.
