举一反三
- Any number that can be represented as a decimal fraction can be represented exactly in floating point representation in Python.
- Assume that a floating point number is represented in binary. If the<br/>sign bit is 1, the() A: number is negative B: number is positive C: exponent is negative D: exponent is positive
- 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.
