Mod 2 and Mod 4 ? Yeah sure

pawn Код:

if( !(iValor % 2) || !(iValor % 3) || !(iValor % 4) || (iValor == 1)) return false;

Can iValor ever be iCount if iCount needs to be smaller than the square root of iValor ? Of course

pawn Код:

while(iCount++ < floatsqroot(iValor))  
    if( !(iValor % iCount) && (iValor != iCount) ) return false;

So lets present my version

pawn Код:

stock IsPrime(value)
{
    if((value < 4) || (value & 0b1) == 0) {
        if((value == 2) || (value == 3)) {
            return true;
        }
        return false;
    }
    new
        i = floatround(floatpower(value, 0.5), floatround_floor);
    if((i & 0b1) == 0) {
        i--;
    }
    while(i > 2) {
        if((value % i) == 0) {
            return false;
        }
        i -= 2;
    }
    return true;
}

Criticism is allowed


I dont know if thats faster but

pawn Код:

stock DecimalToBinary(const iNum) 
{
    new string[cellbits + 1];
    format(string, sizeof string, "%b", iNum);
    return strval(iNum);
}
