Hi
Where the 'constant' (h) gets assigned it's value?
The h is actually counting the number of folders from other variables.
What do you think the value of '$t' in 'sqrt($t)' is?
Why are you trying "pipe" 'sqrt($t)' into 'bc -l'? Wouldn't a simple 't=sqrt(t)' be enough?
Yeah. I already tried on sqrt(t); which is without bc -l.
You are right. I am using associative array count for the purpose to read each line.
However, when I get the result from the operation, it doesnt return me the correct output from these operation.Did I missed out any "$" in the below fragment of code? It gives me INF and NAN value
cat a.txt| awk ' {
t= h*($3+$2);
s= sqrt($t)
count($1)=$2/s
}
END{
printf("the sqrt of %d is %d\n", $2,$1);
}
Please advise.Thanks.
Rgrds,
Jason

sqrt(3M) sqrt(3M)
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.
