How to convert ansible string to float and use that value to compare with float value

Question

I want to convert Ansible string value to float and compare with another float value

In my ini file bin_version=6.5.17 I want to compare bin_version with 1 decimal value(6.5 >= 6.7) so I'm splitting it with 1 decimal value bin_version.split('.')[:2] and joining it with float "{{bin_version.split('.')[:2] | join('.')|float}}"

But it's not working as expected with when condition when: version >= 6.7, Does it float conversion(|float) really working here ?

tasks:
  - set_fact:
      version: "{{bin_version.split('.')[:2] | join('.')|float}}"

  - debug:
      msg: "{{version}}"
    when: version >= 6.7

task should be only executed when version >= 6.7

But

Case: 1: Pass

  when: version >= 6.7 // 6.5 >= 6.7

Expected result is task should be skipped but it's executing.

You have to compare as below

when: bin_version is version('6.7', '>=')

I think you need not convert to float. – Smily Oct 14 '19 at 13:25
Yes you're right float type conversion is not required. Thanx – sanjayshr Oct 14 '19 at 14:04
failed. The error was: Version comparison: 'StrictVersion' object has no attribute 'version'\n\n I'm getting this error. – Dayanand Dhumala May 04 '22 at 15:32
