HYPOT(3) BSD Library Functions Manual HYPOT(3)NAME
hypot -- euclidean distance function
SYNOPSIS
#include <math.h>
double
hypot(double x, double y);
long double
hypotl(long double x, long double y);
float
hypotf(float x, float y);
DESCRIPTION
The hypot() function computes the sqrt(x*x+y*y) without undue overflow or underflow.
SPECIAL VALUES
hypot(x, y) , hypot(y, x) , and hypot(x, -y) are equivalent.
hypot(x, +-0) is equivalent to fabs(x).
hypot(+-infinity, y) returns +infinity even if y is a NaN.
SEE ALSO cabs(3), math(3), sqrt(3)STANDARDS
The hypot() function conforms to ISO/IEC 9899:2011.

HYPOT(3) BSD Library Functions Manual HYPOT(3)NAME
hypot, hypotf, hypotl, cabs, cabsf, cabsl -- Euclidean distance and complex absolute value functions
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
#include <math.h>
double
hypot(double x, double y);
float
hypotf(float x, float y);
long double
hypotl(long double x, long double y);
#include <complex.h>
double
cabs(double complex z);
float
cabsf(float complex z);
long double
cabsl(long double complex z);
DESCRIPTION
The hypot(), hypotf() and hypotl() functions compute the sqrt(x*x+y*y) in such a way that underflow will not happen, and overflow occurs only
if the final result deserves it. The cabs(), cabsf() and cabsl() functions compute the complex absolute value of z.
hypot(infinity, v) = hypot(v, infinity) = +infinity for all v, including NaN.
ERROR (due to Roundoff, etc.)
Below 0.97 ulps. Consequently hypot(5.0, 12.0) = 13.0 exactly; in general, hypot and cabs return an integer whenever an integer might be
expected.
NOTES
As might be expected, hypot(v, NaN) and hypot(NaN, v) are NaN for all finite v. But programmers might be surprised at first to discover that
hypot(+-infinity, NaN) = +infinity. This is intentional; it happens because hypot(infinity, v) = +infinity for all v, finite or infinite.
Hence hypot(infinity, v) is independent of v. Unlike the reserved operand fault on a VAX, the IEEE NaN is designed to disappear when it
turns out to be irrelevant, as it does in hypot(infinity, NaN).
SEE ALSO carg(3), math(3), sqrt(3)STANDARDS
The hypot(), hypotf(), hypotl(), cabs(), cabsf(), and cabsl() functions conform to ISO/IEC 9899:1999 (``ISO C99'').
HISTORY
Both a hypot() function and a cabs() function appeared in Version 7 AT&T UNIX.

Hello life savers!!
Is there any way to use substr in awk command for returning one part of a string from declared start and stop point?
I mean I know we have this:
substr(string, start, length)
Do we have anything like possible to use in awk ? :
substr(string, start, stop)

I want to join two files , with file 1 col 3 and file 2 col 1 as key.
The join command is erratic for some reason. File 2 is a master file having all the names, and file 1 has some values. I want to add the names from fil2 in file 1. If I use the original master file, some output is missing.

under past circumstances, id be fine running commands like this:
case 1:
printf '%s\n' "${MASSIVETEXT}" | egrep "i am on the first line"
case 2:
vprintf '%s\n' "${MASSIVETEXT}" | egrep -v "i am on the first line"
This works fine. Bit it calls external utility "egrep" and "printf". ... (5 Replies)
