Explanation 10

Divide floating type by integer type

This program divides the literal floating value of 1.0 by the literal integer value of 3 (no decimal point is specified in the integer literal value) .

Automatic conversion from narrow to wider type

To begin with, whenever division is performed between a floating type and an integer type, the integer type is automatically converted (sometimes called promoted) to a floating type and floating arithmetic is performed.

What is the actual floating type, float or double?

The real question here is, what is the type of the literal shown by 1.0 (with a decimal point separating the 1 and the 0) . Is it a double or a float ?

Type double is the default

By default, a literal floating value is treated as a double .

The result is type double

Consequently, this program divides a double type by an integer type, producing a result of type double . This is somewhat evident in the output, which shows about 17 digits plus a decimal point in the result. (Recall that the maximum value for a float shown earlier had only about eight digits plus thedecimal point and the exponent.)

How can you create literals of type float?

What if you don't want your literal floating value to be treated as a double , but would prefer that it be treated as a float instead.

You can usually force this to be the case by adding a suffix of either F or f to the end of the literal value (as in 1.0F) . If you were to modify this program to cause it to divide 1.0F by 3, the output would be 0.33333334 withonly nine digits in the result.

are nano particles real
yeah
Joseph
Hello, if I study Physics teacher in bachelor, can I study Nanotechnology in master?
no can't
Lohitha
where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
learn
da
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts
Bhagvanji
hey

da
Application of nanotechnology in medicine
has a lot of application modern world
Kamaluddeen
yes
narayan
what is variations in raman spectra for nanomaterials
ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
