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:
-
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 literal1.0
represents aDouble
value of 1.0. -
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 theDouble
value 1.234 x 10^(-10). -
Floats : Floats are represented with the suffix
f
orF
.They are represented as single-precision floating-point numbers. Floats have a smaller range and precision than doubles. For example, the literal728832f
represents aFloat
value of 728832.0. -
Floats with Exponents: Floats can also be written using scientific notation, similar to doubles. The literal
7.28832e5F
represents theFloat
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
