Consider three registers R1, R2 and R3 that store numbers in IEEE-754 single precision floating point format. Assume that R1 and R2 contain the values (in hexadecimal notation) 0x42200000 and 0xC1200000, respectively.

If R3 = $${{R1} \over {R2}}$$, what is the value stored in R3?

If R3 = $${{R1} \over {R2}}$$, what is the value stored in R3?
