Axis won't use decimal point values for scaling

Hey guys, I want to make the y axis ticks be in the step size of the max value (e.g. if the max value is 10, the ticks are 0, 2.5, 5, 7.5, 10). However it’s rounding up and I’m not sure how to prevent that. Option used:

Expected Behavior

Steps to have decimal values: [0, 2.5, 5, 7.5, 10]

Current Behavior

Steps get rounded up to : [0, 3, 5, 8, 10].

Steps to Reproduce (for bugs)

1. Make sample chart with any data and use the following scale option: scales: { yAxes: [{ ticks: { min: 0, max: 10, stepSize: 2.5, display: true, beginAtZero: true } }] }

Context

I want to be able to set the step size to any value I want and be able to scale properly. Currently when it automatically rounds up, it looks off and it’s not the result I want anyway.

Environment

• Chart.js version: 2.6
• Browser name and version: Nodejs 9

This is resolved by #4841. Set ticks.precision to 1.

This was not fixed in #4841 because ticks.precision is effective only if stepSize is not specified. I created a new PR #5786.
