Re: [Haskell-beginners] How to convert a float or double number into a string?

Thishttps://github.com/eccstartup/numberToText/blob/master/src/Text/New/NumberTo...is my poor code. *show* function truncated these digits. On Wed, Sep 18, 2013 at 11:07 PM, yi lu wrote:

You are right! I hope to input a number, for example 123, and output its text "one hundred and twenty-three". So, for 1.23456789012345678901, I want the result is "one point two three four five six ...(something omitted)". I can define a funciton, say "toText", to preform this action. In ghci, I can use like this. Prelude>toText 123.45 "one hundred and twenty-three point four five"

However, in this function, I have to read this number as String(originally a number, now "123"), and make it to words(String) like "one two three". But for a float number, it will not work very well. Prelude>toText 1.23456789012345678901 "(a truncated answer)"

This confuses me!

In fact, I am not looking for some way to convert a float 0.75 to 3%4.

Your reply is helpful!

What I need is just as much number of digits as possible. If I can hold as many digits of pi, i.e. 3.1415926535... as possible and save it in a String, it will be perfect!

I think something is still missing from your description.

If you want to store the digits of pi in a string then why not use a string?
