Problem Statement

Programming languages have different ways of expressing floating-point literals.

Show how floating-point literals can be expressed in your language: decimal or other bases, exponential notation, and any other special features. You may want to include a regular expression or BNF/ABNF/EBNF defining allowable formats for your language.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Literals/Floating point step by step in the Kotlin programming language

In Kotlin, numeric literals can be represented using different types of formats:

  1. Decimals (Double): Decimals are represented by default as Double type. These literals can be written as a sequence of digits, optionally followed by a decimal point and more digits. For example, the literal 1.0 represents a Double value of 1.0.

  2. Decimals with Exponents (Double): Decimals can also be written using scientific notation, where the number is represented as a decimal multiplied by a power of 10. For example, the literal 1.234e-10 represents the Double value 1.234 x 10^(-10).

  3. Floats : Floats are represented with the suffix f or F.They are represented as single-precision floating-point numbers. Floats have a smaller range and precision than doubles. For example, the literal 728832f represents a Float value of 728832.0.

  4. Floats with Exponents: Floats can also be written using scientific notation, similar to doubles. The literal 7.28832e5F represents the Float value 7.28832 x 10^(5).

Source code in the kotlin programming language

val d = 1.0 // Double
val d2 = 1.234e-10 // Double
val f = 728832f // Float
val f2 = 7.28832e5F // Float
