Hello,
I kinda newbie in unix so I would like so help.I know that there is a command that compares two integer numbers test (eg. #$1=0 ).I would like to know if it is possible to compare any number with another (eg. 2.3=0 or 3.7!=0 4.5>2.2).
Thank you in advance. (1 Reply)
Hello, I'm searching for a quick method to read numeric values from a file or a defined variable and identifying the largest number. For instance if the following numbers are in a file or defined to a variable:
09192007 09202007 09182007 09172007 09162007

Hi!
I've come up with a ksh-script that produces one or more lists of hosts.
At the and of the script, I would like to print only those hosts that exists in all the lists.
Ex.
HOSTS="host1 host2 host3 host11"
HOSTS="host1 host2 host4"
HOSTS="host2 host11"
HOSTS="host2 host5 host6 host7... (1 Reply)
Hi,
I am a noob at shell scripting.
basically I am trying to compare row counts from 8 tables in different databases. I have managed to get the row counts using awk from the spool files for both databases.

Im trying to compare two numbers with decimals but its not working as expected.
a=1
b=1.1
if
then echo "equal"
fi
When I do this it says that the numbers are equal. Ultimately Im using -le and -ge in the if statements but I tested with -eq for simplicity.
Any way to make this... (3 Replies)

Module Complex
: sig end
Complex numbers.
This module provides arithmetic operations on complex numbers. Complex numbers are represented by their real and imaginary parts (carte-
sian representation). Each part is represented by a double-precision floating-point number (type float ).
type t = {
re : float ;
im : float ;
}
The type of complex numbers. re is the real part and im the imaginary part.
val zero : t
The complex number 0 .
val one : t
The complex number 1 .
val i : t
The complex number i .
val neg : t -> t
Unary negation.
val conj : t -> t
Conjugate: given the complex x + i.y , returns x - i.y .
val add : t -> t -> t
Addition
val sub : t -> t -> t
Subtraction
val mul : t -> t -> t
Multiplication
val inv : t -> t
Multiplicative inverse ( 1/z ).
val div : t -> t -> t
Division
val sqrt : t -> t
Square root. The result x + i.y is such that x > 0 or x = 0 and y >= 0 . This function has a discontinuity along the negative real axis.
val norm2 : t -> float
Norm squared: given x + i.y , returns x^2 + y^2 .
val norm : t -> float
Norm: given x + i.y , returns sqrt(x^2 + y^2) .
val arg : t -> float
Argument. The argument of a complex number is the angle in the complex plane between the positive real axis and a line passing through
zero and the number. This angle ranges from -pi to pi . This function has a discontinuity along the negative real axis.
val polar : float -> float -> t
polar norm arg returns the complex having norm norm and argument arg .
val exp : t -> t
Exponentiation. exp z returns e to the z power.
val log : t -> t
Natural logarithm (in base e ).
val pow : t -> t -> t
Power function. pow z1 z2 returns z1 to the z2 power.
