Question regarding face value of a bond in calculation

CFA Level I Quant
#1

I know i am probably really screwed if i am still asking this question up till this point:

I always calculate my face value of a bond assuming its 1000, i realise that some of the practice question uses the face value of 100 and as a result my solution for example in the calculation of the EAY, is 1 decimal point smaller. Is there any rule that i am suppose to use the FV of 100 instead of 1000?

#2

If the PV is close to 1000…use 1000.

If the PV is close to 100…use 100.

#3

There is no rule, but you better be sure that you’re assuming the correct magnitude when inputting the numbers into your calculation and answering the questions.

Thanks guys haha
