[ruby-core:117132] [Ruby master Bug#20334] Time.to_i truncates a fractional timestamp instead of rounding up
Issue #20334 has been reported by werelnon (Malcolm Patterson). ---------------------------------------- Bug #20334: Time.to_i truncates a fractional timestamp instead of rounding up https://bugs.ruby-lang.org/issues/20334 * Author: werelnon (Malcolm Patterson) * Status: Open * ruby -v: 3.2.2 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- Simple steps that can be executed in a ruby interactive shell ``` irb(main):007> t = Time.now => 2024-03-14 00:23:55.983885525 +0000 irb(main):008> t.to_f => 1710375835.9838855 irb(main):009> t.to_i => 1710375835 ``` Based on the example the result of `t.to_f.round` is the better result? -- https://bugs.ruby-lang.org/
Issue #20334 has been updated by nobu (Nobuyoshi Nakada). Status changed from Open to Feedback It is the intended behavior. http://ruby-doc.com/3.2.2/Time.html#class-Time-label-Epoch+Seconds
Other retrieval methods such as `Time#to_i` and `Time#to_f` may return a value that rounds or truncates subseconds.

Issue #20334 has been updated by werelnon (Malcolm Patterson). Bit vague to say in the docs that `to_i` and `to_f` "may return a value that rounds or truncates". Why not just say it truncates? Regardless, I can live with it :) ---------------------------------------- Bug #20334: Time.to_i truncates a fractional timestamp instead of rounding up https://bugs.ruby-lang.org/issues/20334#change-107258 * Author: werelnon (Malcolm Patterson) * Status: Feedback * ruby -v: 3.2.2 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- Simple steps that can be executed in a ruby interactive shell ``` irb(main):007> t = Time.now => 2024-03-14 00:23:55.983885525 +0000 irb(main):008> t.to_f => 1710375835.9838855 irb(main):009> t.to_i => 1710375835 ``` Based on the example the result of `t.to_f.round` is the better result? -- https://bugs.ruby-lang.org/
