PHP Code:

stock bool:is_str_float(const string[])
{
    new c, i, p;
    while(is_char(c = string[i++]))
    {
        if(!isdigit(c))
        {
            if(c != '.' || p)
            {
                return false;
            }
            
            p = 1;
        }
    }
    
    return (i > 1);
}
