NAME
fmod -- floating-point remainder function SYNOPSIS
#include <math.h> double fmod(double x, double y); float fmodf(float x, float y); DESCRIPTION
The fmod() and fmodf() functions compute the floating-point remainder of x/ y. Specifically, the functions return the value x-i*y, for some integer i such that, if y is non-zero, the result has the same sign as x and magnitude less than the magnitude of y. SPECIAL VALUES
fmod(+-0, y) returns +-0 for y not zero. fmod(x, y) returns a NaN and raises the "invalid" floating-point exception for x infinite or y zero. fmod(x, +-infinity) returns x for x not infinite. SEE ALSO
math(3) STANDARDS
The fmod() and fmodf() functions conform to ISO/IEC 9899:1999(E). BSD

NAME
fmod -- floating-point remainder function SYNOPSIS
#include <math.h> double fmod(double x, double y); long double fmodl(long double x, long double y); float fmodf(float x, float y); DESCRIPTION
The fmod() functions compute the floating-point remainder of x/ y. Specifically, the functions return the value x-i*y, for some integer i such that, if y is non-zero, the result has the same sign as x and magnitude less than the magnitude of y. SPECIAL VALUES
fmod(+-0, y) returns +-0 if y is neither 0 nor NaN. fmod(x, y) returns a NaN and raises the "invalid" floating-point exception for x infinite or y zero. fmod(x, +-infinity) returns x for x not infinite. VECTOR OPERATIONS
If you need to apply the fmod() 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 vfmodf(vFloat x, vFloat y); void vvfmodf(float *z, const float *y, const float *x, const int *n); void vvfmod(double *z, const double *y, const double *x, const int *n); SEE ALSO
math(3) STANDARDS
The fmod() 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 (3 Replies)
