The Past, The Present And The Future With Ceilings And Floors

$\Large \frac { \left\lceil \frac { 2015^{ \frac { 2015 }{ 2016 } } }{ 2016^{ \frac { 2016 }{ 2017 } } } \right\rceil }{ \left\lfloor \frac { { 2016 }^{ \frac { 2017 }{ 2016 } } }{ { 2015 }^{ \frac { 2016 }{ 2015 } } } \right\rfloor } =?$

Note : $\left\lceil x \right\rceil$ denotes the ceiling function and $\left\lfloor x \right\rfloor$ denotes the floor function. The fractions represent powers.
