Question

im just a beginner for studing computer this semister....should anyone tell me..the uses of these data types in the program.."floating-point,interger datas,sign and unsign data types,and how these are used in the program...and can you give me there uses in the program as an example???...mostly explaination..

Answer 1

Basically, floating point numbers (aka floats) are rational numbers that have a decimal point
Ex: 10.7, 4.6, 3.2
Integers are whole numbers
Ex: 10, 9 , 4
The thing about it, if you enter a decimal (for example 10.7) but AS an integer, Python will discard(neglect) the decimal point/fraction and consider 10.7=10

Also, unless you state that the number you're writing is a float(by adding the decimal point or writing b4 the function <float>), Python will consider it as integer by default.

Codes for example:
x=float(10)
print x

--> it will print 10.0

y=int(12.5)
print y

--> it will print only 12 because by writing int you stated that it's a whole number not a decimal.

I'm afraid I don't know what sign and 'unsign' data types are.
Hope I helped ;)
