The built-in sprintf implements round-to-even already: 
for (qw(1.0049 1.0050 1.0051 1.0149 1.0150 1.0151 1.0249 1.0250 1.0251
+)) {
  printf "%s => %0.2f\n", $_, $_;
}
...
1.0049 => 1.00
1.0050 => 1.00
1.0051 => 1.01
1.0149 => 1.01
1.0150 => 1.01
1.0151 => 1.02
1.0249 => 1.02
1.0250 => 1.02
1.0251 => 1.03
