A floating point number is, in normal mathematical terms, a real number. It's of the form: 1.0, 64.369, -55.5555555, and so forth. It basically means that the number can have a number a digits after a decimal point.
A float is a programming language's high-level representation of the machine-level notion of a single-precision floating point value. In most cases, the machine-level representation is implemented according to the 32-bit IEEE 754 single-precision binary floating-point format.
it can support a much wider range of values.

It depends on the particular implementation's representation of integer and floating point number. The IEEE 754-2008 standard provides four basic resolutions, 16 bits (not common), 32 bit, 64 bits, and 128 bits (also not common). At the same time, integers can be 8 bits, 16 bits, 32 bits, 64 bits (in 64 bit platforms and some libraries on 32 bit platforms) and 128 bits (not common). In general, if you want to keep resolution down to the units digit, you can store a larger number in an integer than you can in a floating point, due to overhead in the exponent, but, at the same time, due to the scalability of floating point numbers, you can store larger numbers in floating point numbers if you are willing to lose resolution on the low-order end.
It is somewhat complicated (search for the IEEE floating-point representation for more details), but the basic idea is that you have a few bits for the base, and a few bits for the exponent. The numbers are stored in binary, not in decimal, so the base and the exponent are the numbers "a" and "b" in a x 2b.
It's a tricky area: Decimal numbers can be represented exactly. In contrast, numbers like 1.1 do not have an exact representation in binary floating point. End users typically would not expect 1.1 to display as 1.1000000000000001 as it does with binary floating point. The exactness carries over into arithmetic. In decimal floating point, 0.1 + 0.1 + 0.1 - 0.3 is exactly equal to zero. In binary floating point, the result is 5.5511151231257827e-017. While near to zero, the differences prevent reliable equality testing and differences can accumulate. For this reason, decimal is preferred in accounting applications which have strict equality invariants. So you have to be carefull how you store floating point decimals in binary. It can also be used in a fraction. It must be simplufied then reduced and multiplied.

"Floating Point" refers to the decimal point. Since there can be any number of digits before and after the decimal, the point "floats". The floating point unit performs arithmetic operations on decimal numbers.
Floating point numbers are typically stored as numbers in scientific notation, but in base 2. A certain number of bits represent the mantissa, other bits represent the exponent. - This is a highly simplified explanation; there are several complications in the IEEE floating point format (or other similar formats).Floating point numbers are typically stored as numbers in scientific notation, but in base 2.

A method for storing and calculating numbers in which the decimal points do not line up as in fixed point numbers. The significant digits are stored as a unit called the "mantissa," and the location of the radix point (decimal point in base 10) is stored in a separate unit called the "exponent." Floating point methods are used for calculating a large range of numbers quickly. Floating point operations can be implemented in hardware (math coprocessor), or they can be done in software. In large systems, they can also be performed in a separate floating point processor that is connected to the main processor via a channel.
I believe it is the floating-point.
floating point numbers, mainly.
In Computing, Floating Point refers to a method of representing an estimate of a real number in a way which has the ability to support a large range of values.
