You write 1 6 as 1.6 in decimal form. Rewrite in Standard Form (6-i)/(1+i) Multiply the numerator and denominator of by the conjugate of to make the denominator real. Tap for more steps. Simplify the numerator. Tap for more steps. Expand using the FOIL Method. Tap for more steps. Apply the distributive property. In Britain this is another name for Scientific Notation, where you write down a number this way: In this example, 5326.6 is written as 5.3266 × 10 3, because 5326.6 = 5.3266 × 1000 = 5.3266 × 10 3. In other countries it means 'not in expanded form' (see Composing and Decomposing Numbers). Step 1: Multiply the denominator (the bottom number in the fraction) and the whole number 9 × 3 = 27. Step 2: Add the answer from Step 1 to the numerator (the top number in the fraction) 27 + 5 = 32. Step 3: Write answer from Step 2 over the denominator.
write() writes up to count bytes from the buffer pointed buf to the filereferred to by the file descriptor fd.
The number of bytes written may be less than count if, for example, there is insufficient space on the underlying physical medium, or theRLIMIT_FSIZE resource limit is encountered (see setrlimit(2)), or the call was interrupted by a signal handler after having written lessthan count bytes. (See also pipe(7).)
For a seekable file (i.e., one to which lseek(2) may be applied, for example, a regular file) writing takes place at the current file offset,and the file offset is incremented by the number of bytes actually written. If the file was open(2)ed with O_APPEND, the file offset isfirst set to the end of the file before writing. The adjustment of the file offset and the write operation are performed as an atomic step.
POSIX requires that a read(2) which can be proved to occur after a write() has returned returns the new data. Note that not all filesystems are POSIX conforming.
Return Value
On success, the number of bytes written is returned (zero indicates nothing was written). Onerror, -1 is returned, and errno is set appropriately.
If count is zero and fd refers to a regular file, then write() may return a failure status if one of the errors below is detected. Ifno errors are detected, 0 will be returned without causing any other effect. If count is zero and fd refers to a file other than a regular file,the results are not specified.
Errors
fd has been exhausted.
EFAULT
buf is outside your accessible address space.
EFBIG
An attempt was made to write a file that exceeds the implementation-defined maximum file size or the process's file size limit, or to write at a positionpast the maximum allowed offset.
EINTR
The call was interrupted by a signal before any data was written; see signal(7).
EINVAL
fd is attached to an object which is unsuitable for writing; or the file was opened with the O_DIRECT flag, and either the address specifiedin buf, the value specified in count, or the current file offset is not suitably aligned.
EIO
A low-level I/O error occurred while modifying the inode.
ENOSPC
The device containing the file referred to by fd has no room for the data.
EPIPE
fd is connected to a pipe or socket whose reading end is closed. When this happens the writing process will also receive a SIGPIPE signal.(Thus, the write return value is seen only if the program catches, blocks or ignores this signal.)
Other errors may occur, depending on the object connected to fd.
Conforming to
SVr4, 4.3BSD, POSIX.1-2001.
Under SVr4 a write may be interrupted and return EINTR at any point, not just before any data is written.
Notes
A successful return from write() does not make any guarantee that data has been committed todisk. In fact, on some buggy implementations, it does not even guarantee that space has successfully been reserved for the data. The only way to be sure is tocall fsync(2)
How Would You Write 1 1/6 As A Decimal
after you are done writing all your data.
If a write() is interrupted by a signal handler before any bytes are written, then the call fails with the error EINTR; if it is interruptedafter at least one byte has been written, the call succeeds, and returns the number of bytes written.
