When .9432 E – 4 is subtracted from .5452 E – 3 in normalized floating point mode

.5452 E – 3 is changed to 5.452 E – 4 but .9432 E – 4 is not changed

.9432 E – 4 is changed to .09432 E – 3 and .5452 E – 3 is not changed

None of the numbers is changed

Both Ihe numbers are changed and their exponents are, made equal to -5
