Float is a shortened term for “floating point.” By definition, it’s a fundamental data type built into the compiler that’s used to define numeric values with floating decimal points. C, C++, C# and many other programming languages recognize float as a data type.

What is a strings in programming?
Most programming languages have a data type called a string, which is used for data values that are made up of ordered sequences of characters, such as “hello world”. A string can contain any sequence of characters, visible or invisible, and characters may be repeated. A string can be a constant or variable .

What is difference between float and double in C?
Difference between float and double in C/C++ double has 2x more precision then float. float is a 32 bit IEEE 754 single precision Floating Point Number1 bit for the sign, (8 bits for the exponent, and 23* for the value), i.e. float has 7 decimal digits of precision.
What is a float in coding?
In computer science, a float is a data type composed of a number that is not an integer, because it includes a fraction represented in decimal format. Some point out that the float data type is used in computer programming when more precision is needed than what integers can provide.

What is the difference between float and double in C++?
Float and double are similar types. Float is a single-precision, 32-bit floating point data type; double is a double-precision, 64-bit floating point data type. The biggest differences are in precision and range. Double: The double accommodates 15 to 16 digits, compared with float’s seven.
