Can we map calculated ratings with custom ranges

Summary: We have 4 points numeric rating model. and in performance documents , when the ratings range is falling between 1.5 to 2.5 then it is mapping to 2, but we need it it like below

1.    if the numeric rating is between 0 - 1.79 then it should be mapped to 1

2.    if the numeric rating is between 1.8 - 2.79 then it should be mapped to 2

3.    if the numeric rating is between 2.8 - 3.79 then it should be mapped to 3

4.    if the numeric rating is between 3.8 - 4 then it should be mapped to 4
