How to create SQRT function in catenate file

HI, I have a file which i catenate and using the fields in the file, I would like to get sqrt of it. I tried to man the function but it normally would need an echo as well as bc. What I am intending to find out is catenate a file where let say cat a.txt| awk ' { t= h*($3+$2); t=...

Q: Is SQRT(n) possible in a POSIX compliant shell? A: Yes within limits.

Hi all... This is just a fun project to see if it is possible to get a square root of a positive integer from 1 to 9200000 to 6 decimal places on a 64 bit architecture machine. It is coded around dash and the results show the values from 0 to 10000. Complex numbers can easily be catered for by...

NAME

       sqrt(), sqrtf(), sqrtl(), sqrtw(), sqrtq() - square root functions

SYNOPSIS

   HP Integrity Server Only
DESCRIPTION

       returns the non-negative square root of x.

       is a version of it takes a argument and returns a result.

   Integrity Server Only
       is a version of it takes a argument and returns a result.

       is an version of it takes an argument and returns an result.

       is equivalent to on HP-UX systems.

USAGE

       To use these functions compile either with the default option or with the and the options.

       To use (for Integrity servers) or compile also with the option.

       To use any of these functions, make sure your program includes and link in the math library by specifying on the compiler or linker command
       line.

       For more information, see the at the following site:

RETURN VALUE

       If x is +INFINITY, returns +INFINITY.

       If x is NaN, returns NaN.

       If x is less than zero, returns NaN and raises the invalid floating-point exception.

       raises the inexact exception whenever a rounded result does not equal the mathematical result.

ERRORS

       If x is less than zero, sets to [EDOM].

   Integrity Server Only
       HP-UX functions on Integrity servers do not set by default.  For setting, compile with the option and the (default) option.
