pgpromise converting number to string

Question

i use a select from my database with pg-promise to send my data into a server and use this data in my web application, but the numbers coluns, like a aggregation functions are formatting as string in my server,:
Follow the code and sorry for bad english:

const pgp = require("pg-promise")();
const database = require("./DataBase");

exports.ChequeGrouped = function (cheque) {
  let Select = `
SELECT     
    COALESCE(nome_devedor, '_TOTAL') AS nome_devedor,
    CAST(SUM(valor_titulo) as numeric) AS valor_titulo,
    COUNT(id_movimento_cheque) AS contagem_movimento
FROM public.__vwfw_movimento_cheque
    WHERE  tipo_movimento = 2 
        AND  nome_devedor ILIKE $1
    GROUP BY nome_devedor
    ORDER BY nome_devedor desc    `;
 return database.manyOrNone(Select, cheque);
}

i receive all data as string format,
