remquo(3)


NAME

   remquo, remquof, remquol - remainder and part of quotient

SYNOPSIS

   #include <math.h>

   double remquo(double x, double y, int *quo);
   float remquof(float x, float y, int *quo);
   long double remquol(long double x, long double y, int *quo);

   Link with -lm.

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

   remquo(), remquof(), remquol():
       _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L

DESCRIPTION

   These  functions  compute  the  remainder and part of the quotient upon
   division of x by y.  A few bits of the quotient are stored via the  quo
   pointer.  The remainder is returned as the function result.

   The  value  of  the  remainder  is  the  same  as  that computed by the
   remainder(3) function.

   The value stored via the quo pointer has the sign of x / y  and  agrees
   with the quotient in at least the low order 3 bits.

   For  example,  remquo(29.0, 3.0)  returns -1.0 and might store 2.  Note
   that the actual quotient might not fit in an integer.

RETURN VALUE

   On success, these functions return the  same  value  as  the  analogous
   functions described in remainder(3).

   If x or y is a NaN, a NaN is returned.

   If  x  is an infinity, and y is not a NaN, a domain error occurs, and a
   NaN is returned.

   If y is zero, and x is not a NaN, a domain error occurs, and a  NaN  is
   returned.

ERRORS

   See  math_error(7) for information on how to determine whether an error
   has occurred when calling these functions.

   The following errors can occur:

   Domain error: x is an infinity or y is 0, and the other argument is not
   a NaN
          An invalid floating-point exception (FE_INVALID) is raised.

   These functions do not set errno.

VERSIONS

   These functions first appeared in glibc in version 2.1.

Opportunity


Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. 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.
