fix: resolve multiple bugs in commitpulse

[saurabhhhcodes]

Description

This PR fixes real bugs found in the codebase:

• Added Number.EPSILON to Math.round: prevents floating-point drift (e.g. 1.005 * 100 rounding to 100 instead of 101).
• Replaced arr[arr.length - 1] with .at(-1): cleaner access to the last element.
• Replaced global isNaN with Number.isNaN: the global version coerces its argument, so isNaN('1') returns false while Number.isNaN is strict.
• Added explicit radix to parseInt: without 10, strings like '0x1F' or '08' parse in unintended bases.

Type of Change

• Bug fix (non-breaking change fixing an issue)

How Has This Been Tested?

• Local manual testing

Checklist

• My code follows the style guidelines
• I have performed a self-review
