NAME
ecvt_r, fcvt_r, qecvt_r, qfcvt_r − convert a floating-point number to a string
SYNOPSIS
#include <stdlib.h>
int
ecvt_r(double number, int
ndigits, int *decpt,
int *sign, char *buf, size_t
len);
int
fcvt_r(double number, int
ndigits, int *decpt,
int *sign, char *buf, size_t
len);
int
qecvt_r(long double number, int
ndigits, int *decpt,
int *sign, char *buf, size_t
len);
int
qfcvt_r(long double number, int
ndigits, int *decpt,
int *sign, char *buf, size_t
len);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
ecvt_r(), fcvt_r(), qecvt_r(), qfcvt_r():
_SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE >= 500
DESCRIPTION
The functions ecvt_r(), fcvt_r(), qecvt_r() and qfcvt_r() are identical to ecvt(3), fcvt(3), qecvt(3) and qfcvt(3), respectively, except that they do not return their result in a static buffer, but instead use the supplied buf of size len. See ecvt(3) and qecvt(3).
RETURN VALUE
These functions return 0 on success, and −1 otherwise.
CONFORMING TO
These functions are GNU extensions.
NOTES
These functions are obsolete. Instead, sprintf(3) is recommended.

Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.
Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.
Free Software
Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.
Free Books
The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.
Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
Education
Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.
Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
