title: JuliaLang plot with large xtick label numbers is displayed with too many figures in scientific notation and malformed exponent
body: <p>I am using <code>Plots.jl</code> with the default GR() plotting backend rather than pyplot from <code>JuliaLang</code>. The x-axis tick numbers are in the thousands and the series plot produced uses scientific notation <a href="https://en.wikipedia.org/wiki/Scientific_notation" rel="nofollow noreferrer">wiki examples</a> to display these numbers on the x-axis. Too many decimal points are given which is understandable since the axis point chosen is set by the program, but even for <code>1.00000x10</code> these trailing zeros are printed. Below is an example and a mistake in the exponentiation is produced. How can this be fixed. The fontfamily was even changed to see if the effect is removed but it remains. (<code>xticks=1:step:final</code>)
