Getting to Know More About the Float Function in C++ Programming Language

For those of you who are interested in learning the C++ programming language, you should also understand the float function in C++. Where float is a data type that will later be used to perform floating point data and numbers for exponential or decimal values. For more details, just look at the information as below.

What is the Float Data Type in C++?

Before looking at the float function in the C programming language, it's good for you to see what float actually means. Where this float data type will also be used to accommodate fractional numbers such as 3, 14 to 62 and 22 or it can be -0.01234.

Apart from that, it's the same with other programming languages, where you can use a full stop, which is used as a separator between integers and fractions. Remember, not using a comma, but a period (.).

Not only that, the float in the C++ include language also has a double data type that can be used to store fractional numbers. However, the difference between float and double lies in the range of numbers and also the level of accuracy of the numbers to be used.

Float Function In C ++

It is important for you to know that this float has its own function, namely as a numeric data type, which will allow you to store various values in the form of fractions or real numbers. Then for the written form of this float, for example like float register_variabel = initialization and for example it can be like float p=3.14;

What is the Difference Between Float and Double C++?

As you know that C++ float and C++ double when viewed in general do have almost the same function. However, apart from that of course there are some differences that you should know:

Where the float function in C++ has a size of 4 bytes while for double C++ it only has a size of 8 bytes.
Then the float has a precision of 7 decimal digits in general and for double it has a precision of 15 digits.
On the float itself only has a single precision value while double has a double precision value.

Not only that, in this float, if later high precision is no longer needed and the program only requires a large number of decimal numbers, the float will save data sparingly and will not take up a lot of memory. Of course this is different from double, which is more expensive and takes up a lot of space. Examples include financial reports and transactions, currency conversion, scientific calculations and others.

So, that's important information about the float function in C++ and also the difference between float and double. Hope it is useful!
