The value twenty point twelve times ten raised to the power of eight should be written as:

• 20E12.8
• 20.12E8.0
• 20.12*10^8
• 20.12E8

The ** operator:

• performs floating-point multiplication
• performs exponentiation
• performs duplicated multiplication
• does not exist

The result of the following division: 1 / 1

• is equal to 1.0
• cannot be predicted
• cannot be evaluated
• is equal to 1

Which of the following statements are true? (Select two answers)

• The right argument of the % operator cannot be zero.
• Addition precedes multiplication.
• The ** operator uses right-sided binding.
