i have a function that convert a number to a letter.
i want to optimise this function. see query: https://dbfiddle.uk/?rdbms=postgres_12&fiddle=2586d3e0b98df1c899defc7b4078e1ef
i want to have decimal part also.
now this function just return integer part.
if i have 203.145, i want to get in letter ‘Two hundred three point one hundred forty-five’,
now this function just return ‘Two hundred three’
