how to add 2 float values to each other?
i tried this and it doesnt work:
#!bin/bash
numone=1.234
numtwo=0.124
total=`expr $numone + $numtwo`
echo $total

Good morning,
I'm testing the use of ceilf:
/*Filename: str.c*/
#include <stdio.h>
#include <math.h>
int main (void)
{
float ceilf(float x);
int dev=3, result=0;
float tmp = 3.444f;
printf("Result: %f\n",ceilf(tmp));
return 0;

Hi all,
I have doubt can array in a shell script can store floating point numbers. i have tired. but i unable to work it out.
Please help me regarding this
Thank U

I wish to give line number from one point to another in sed command like this
sed -n 1,1000000p file1.txt >file2.txt
but variable line number $x,$x+100000 can i give it cos i tried and it was giving an error any suggestions?/
Thx in advance

Hi, i have a simple control like this:
if(sum>1.0)...
If i try to print sum i get 1.000000 but the check returns true. I think it depends on float precision. How can i modify the check?

Hi people :)
I'm learning shell scripting using bash and I want to generate 4 floating point number with 5 decimal places and write them to a file and a variable. I've done all this except the $RAMDOM enviroment variable does not generate a float number but a integrer.
I hope you could... (3 Replies)
if i want to display the contents of a file between say line number 3 and 10 then i use the following command
sed -n '3,10p' filename
if this 3 was contained in x and 10 was contained in y then how wud this command modified?
sed -n '$x,$yp' filename does not work..please advise (2 Replies)
a=1 456
b=4928
c=23
d=456
I want to compare four variables to get the name of the variable having the highest number (2 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.
