EXP(3) BSD Library Functions Manual EXP(3)NAME
exp, exp2, expm1 -- exponential functions
SYNOPSIS
#include <math.h>
double
exp(double x);
float
expf(float x);
double
exp2(double x);
float
exp2f(float x);
double
expm1(double x);
float
expm1f(float x);
DESCRIPTION
The exp() function computes e**x, the base-e exponential of x.
The exp2() function computes 2**x, the base-2 exponential of x.
The expm1() function computes the base-e exponential of x , minus 1 accurately even for very small values of x.
SPECIAL VALUES
exp(+-0) and exp2(+-0) return 1.
exp(-infinity) and exp2(-infinity) return +0.
exp(+infinity) and exp2(+infinity) return +infinity.
expm1(+-0) returns +-0.
expm1(-infinity) returns -1.
expm1(+infinity) returns +infinity.
For all these functions, a range error occurs if the magnitude of x is too large.
SEE ALSO math(3), infnan(3)STANDARDS
The exp() , expf() , exp2() , exp2f() , expm1() , and expm1f() functions conform to ISO/IEC 9899:1999(E).

EXP(3) BSD Library Functions Manual EXP(3)NAME
exp, expf, exp2, exp2f, expm1, expm1f, -- exponential functions
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
#include <math.h>
double
exp(double x);
float
expf(float x);
double
exp2(double x);
float
exp2f(float x);
double
expm1(double x);
float
expm1f(float x);
DESCRIPTION
The exp() and the expf() functions compute the base e exponential value of the given argument x.
The exp2(), and exp2f() functions compute the base 2 exponential of the given argument x.
The expm1() and the expm1f() functions computes the value exp(x)-1 accurately even for tiny argument x.
RETURN VALUES
These functions will return the appropriate computation unless an error occurs or an argument is out of range. The functions exp() and
expm1() detect if the computed value will overflow, set the global variable errno to ERANGE and cause a reserved operand fault on a VAX.
SEE ALSO math(3)STANDARDS
The exp() functions conform to ANSI X3.159-1989 (``ANSI C89''). The exp2(), exp2f(), expf(), expm1(), and expm1f() functions conform to
ISO/IEC 9899:1999 (``ISO C99'').
HISTORY
The exp() functions appeared in Version 6 AT&T UNIX. The expm1() function appeared in 4.3BSD.

Hi,
I have a question.
Im trying to tar a files that the size is bigger that 2 gig.
When i tried to tar it, i got an error says "eached end-of-file before expected"
How can i solve this?
Thanks and Regards (6 Replies)

Hi All,
I'm facing the following issue with my shared libraries in AIX.
memory related calls such as memset, memcpy, malloc etc are failing miserably.
there is something wrong with stack/memory which i can't guess.

hello,
i have a lot of C old code I'm updating to C11 with tgmath.h for generic math. the old code has very specific types, real and complex, like cabsl, csinhl, etc
usually for simple bulk replacements i would do something simple like this
