C -- Copy float to string
-
Hi Friends, I would like to know is there any otherway to copy a double to string in C. I see that it can be done by using sprintf(.. , "%f", .. ) but I want to know anyother way to do this. My problem is: If i run the sprintf (.., "%f", .. ) on any machine in which has decimal point as , (comma) instead of a . (dot) (like French) it is converting . to , in the string even if the double value is having .(dot) . I don't want it to happen. Ur help is highly appreciated.. Thanks a lot.. Regards, Leela

std::istringstream? my mistake, this is C++. useftoa()as an alternative, but never forget that the number is the number. your problem is a matter of representation (the decimal character - '.' or ',' - is not stored in the number itself)
Don't know where to start ?

This is controle by the
LOCALE. I'm not certain that you can force sprintf to a certain representation ( . instead of , ) ?

use ftoa() instead
Such as this implementation?

If I understand you correctly, you want numbers formatted like 123,456.78 regardless of the locale. Is that correct?

Not until
_sprintf_l()came along. That might not be an option for the OP, however.

Hi, Thanks to One and all for trying to help me in this regard,, As of now after copying the double to the string i.e., after sprintf statement Iam checking if string has , using strchr().. If i find a ,(comma) iam replacing it with a . (dot). But if can find some other alternative in which i can copy the value in the double variable as it is to a String.. Btw the double variable has value with .(dot) - Leela

Hi David, I want the double to be stored into the integer string as with decimal point as dot (.) but NOT as a , comma. Regards, Leela
But why would you want to do this for countries that format numbers differently?
