fix bug when the number of segments is integer(line-chunk)

[xiongjiabin]

if numberOfSegments is an integer, like line length is 100, and segmentLength is 10, it's just 10 segments, no need to plus 1 to 11, otherwise will throw an exception later.

@xiongjiabin Why did you close this PR? this looked fine...? just needed a few linting fixes

@xiongjiabin You should need to fix the linting issues:

This should be the code:

    var numberOfSegments = lineLength / segmentLength;

    // If numberOfSegments is integer, no need to plus 1
    if (!Number.isInteger(numberOfSegments)) {
        numberOfSegments = Math.floor(numberOfSegments) + 1;
    }
