Can someone explain what's the difference between 7.0 and 7?

Question

For examle 7.0/2+3.5 and 7/2+3.5 why is this giving different values?

Answer 1

Using dot you say to program that its a float number so he will keep numbers after dot as well ( 7.0/2 = 3.5) otherwise he is working with an integer so (7/2 = 3) =)

Answer 2

Answer 3

7.0 is a float number, whereas 7 is a decimal number. Your output type would be same as your input type:
7.0 / 2 = 3.5
7 / 2.0 = 3.5
7.0 / 2.0 = 3.5
7/2 = 3

Answer 4

Can you share the code with us ?

Answer 5

Data types - the first is float and the second is int🤗

Answer 6

Whenever u see a decimal point then it's a float and returns value in float..
Without decimal point is integer

Answer 7

Krysto Foxik 🐥 Using dot means that it's a *double*, not a *int* or float value.. with an f, it's a float value, for example 7.0f 👌🏻

Answer 8

can you share the code 🤔🤔

Answer 9

My question would be: Is it bad I usually ignore the format of a number/word/text/whatever? (as in float or integer etc...)

Answer 10

The difference is between the data type. '7' is an int, but '7.0' can be float or decimal.
