Floating-point values that appear in source code are known as floating-point literals and are type float by default. ( )
举一反三
- Floating point representation is used to store A: Boolean values B: whole numbers C: real numbers D: integers
- For a floating vessel，the center of flotation is the point in the waterplane（）.
- Which of the following statements is ? ( ) A: Java provides two primitive types for storing floating-point numbers in memory float and double. B: A floating-point number is a number with a decimal point. C: Variables of type float represent single-precision floating-point numbers and have seven significant digits. D: Variables of type float represent double-precision floating-point numbers; these require twice as much memory as double variables.
- You need to store a floating point number，called Tsquare，in the session scope. Which two code snippetsallow you to retrieve this value？（） A: float Tsquare = session.getFloatAttribute（"Tsquare"）； B: float Tsquare = （Float） session.getAttribute（"Tsquare"）； C: float Tsquare = （float） session.getNumericAttribute（"Tsquare"）； D: float Tsquare = （（Float） session.getAttribute.（"Tsquare"））.floatValue（）； E: float Tsquare = （（Float） session.getFloatAttribute.（"Tsquare"））.floatValue；
- Any number that can be represented as a decimal fraction can be represented exactly in floating point representation in Python.
