REMAINDER(3)						   BSD Library Functions Manual 					      REMAINDER(3)

NAME
remainder -- floating-point remainder function SYNOPSIS
#include <math.h> double remainder(double x, double y); float remainderf(float x, float y); DESCRIPTION
The remainder() and remainderf() functions compute the value r such that r = x - n*y, where n is the integer nearest the exact value of x/y. If there are two integers closest to x/y, n shall be the even one. If r is zero, it is given the same sign as x. SPECIAL VALUES
remainder(x, y) returns a NaN and raises the "invalid" floating-point exception if x is infinite or y is 0. SEE ALSO
math(3) STANDARDS
The remainder() and remainderf() functions conform to ISO/IEC 9899:1999(E). BSD

NAME
remainder -- floating-point remainder function SYNOPSIS
#include <math.h> double remainder(double x, double y); long double remainderl(long double x, long double y); float remainderf(float x, float y); DESCRIPTION
The remainder() functions compute the value r such that r = x - n*y, where n is the integer nearest the exact value of x/y. If there are two integers closest to x/y, n shall be the even one. If r is zero, it is given the same sign as x. SPECIAL VALUES
remainder(x, y) returns a NaN and raises the "invalid" floating-point exception if x is infinite or y is 0. NOTE
The drem() function is deprecated. Please use the C99 function remainder() instead. VECTOR OPERATIONS
If you need to apply the remainder() functions to SIMD vectors or arrays, using the following functions provided by the Accelerate.framework may give significantly better performance: #include <Accelerate/Accelerate.h> vFloat vremainderf(vFloat x, vFloat y); void vvremainderf(float *z, const float *y, const float *x, const int *n); void vvremainder(double *z, const double *y, const double *x, const int *n); SEE ALSO
math(3) STANDARDS
The remainder() functions conform to ISO/IEC 9899:2011. BSD

## Shopt -s histappend

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file. # When the shell exits, append to the history file instead of overwriting it shopt -s histappend

## Undeletable file

Greetings, I'm trying to delete a file with a weird name from within Terminal on a Mac. It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘. Here are some examples of what I've tried: 12FX009:5 dpontius\$ ls ââWord FinderÂŽ Plusâ˘ 12FX009:5 dpontius\$ rm...
