cacosh -- complex inverse hyperbolic cosine function
SYNOPSIS
double complex
cacosh(double complex z);
long double complex
cacoshl(long double complex z);
float complex
cacoshf(float complex z);
DESCRIPTION
cacosh(z) computes the inverse hyperbolic cosine of the complex floating-point number z, with a branch cut on the interval [-inf, 1] along
the real axis.
cacosh() returns values in a half-strip of the complex plane with positive real part and imaginary part in the interval [-Pi, Pi].
For all complex floating point numbers z, cacosh(conj(z)) = conj(cacosh(z)).
SPECIAL VALUES
The conjugate symmetry of cacosh() is used to abbreviate the specification of special values.
cacosh(+-0 + 0i) returns 0 + Pi/2 i.
cacosh(x + inf i) returns inf + Pi/2 i, for finite x.
cacosh(x + NaN i) returns NaN + NaN i, for finite nonzero x.
cacosh(-inf + yi) returns inf + Pi i, for finite positive-signed y.
cacosh(inf + yi) returns inf + 0i, for finite positive-signed y.
cacosh(-inf + inf i) returns inf + 3Pi/4 i.
cacosh(inf + inf i) returns inf + Pi/4 i.
cacosh(+-inf + NaN i) returns inf + NaN i.
cacosh(NaN + yi) returns NaN + NaN i, for finite y.
cacosh(NaN + inf i) returns inf + NaN i.
cacosh(NaN + NaN i) returns NaN + NaN i.
NOTES SEE ALSO ccosh(3)complex(3)STANDARDS
The cacosh() function conforms to ISO/IEC 9899:2011.

Hi,
I have the calculations which return me infinity (inf), -inf, other very larger number when I printed them out.
I did try to insert some control condition not to print these out if the above condition is met. The code I implemented is something like:-
for (i=0;i<=1000;i++){

Hi,
Does anyone seem this kind of output from uptime and top where "load average: inf, inf, inf"
is this possible problem with the processor?

Hi all, I was just wondering if there are any consequences, or if its a problem to have a multiple scripts parsing (reading) the same file simultaneously.
For example, I have file.txt with lots of information.
cat script1.sh
grep "awesome" file1.txt > awesome.txt
cat script2.sh
grep -v... (4 Replies)
Hi, all
I have a field in a file looks like this(hundreds of lines):
inf
1.24101
-0.185947
-0.349179
inf
0.126597
0.240142
-0.12031And what I expect is:
inf
1.241
-0.186
-0.349
inf
