How do I convert net pay to string?

void convertNetPay(float netPay, char *netPayString)
{
    int numHuns, numTens, numOnes;
    char OnesTable[9][8]={"One","Two","Three","Four","Five","Six","Seven","Eight","Nine"};
    char ResultString[10+1];
    char TensTable[9][8] = {"Ten","Twenty","Thirty","Forty","Fifty","Sixty","Seventy","Eighty","Ninety"};
    char TeensTable[9][10] {"Eleven","Twelve","Thirteen","fourteen","fifteen","Sixteen","Seventeen","Eighteen","Nineteen"};
    float cents;

    cents = netPay - int(netPay);

    strcpy(netPayString,"The sum of ");

    numHuns = int(netPay) / 100;

    if (numHuns > 0)
    {
    strcat(netPayString,OnesTable[numHuns-1]);
    strcat(netPayString," Hundred ");
    }
    int remainder =  int(netPay) % 100;
    /*if  (remainder ==0)
    {
        //do something
    }*/
         if ((remainder>=11) || (remainder<=19))
        {
            strcat(netPayString, TeensTable[remainder -11]);
        }
            else{
                numTens = int(netPay) % 100 / 10;
                numOnes = int(netPay) % 100 % 10;
                if (numTens > 0)
                {
                    strcat(netPayString,TensTable[numTens -1]);
                    strcat(netPayString," - ");
                }
                if (numOnes > 0)
                {
                    strcat(netPayString,OnesTable[numOnes-1]);
                    strcat(netPayString," Dollars and ");
                }
            cents = cents + 0.005;
            cents = cents * 100;

            sprintf(ResultString,"%d",int(cents));
            strcat(netPayString,ResultString);
            }
}
