关于inkscape:字母’e’在SVG路径中意味着什么?

What does the letter 'e' means inside a SVG path?

通过MDN和W3School,SVG路径中可用的唯一字母(命令)是:M/M(moveto)、L/Z(lineto)、H/H(horizontal lineto)、V/V(vertical lineto)、C/C(curveto)、S/S(smooth curveto)、Q/Q(squared b_zier curveto)、T/T(smooth squared b_zier curveto)、A/A(椭圆弧)和Z/Z(closepath)。

但我刚刚在Inkscape上制作的SVG文件中找到了"e"(2.52e-4,1.13167),我需要知道这意味着什么。完整路径:

PS:代码是在Inkscape上生成的"跟踪位图"的结果。


指数记数法:是的,www.w3schools.com https:/ / / / _ numbers.asp js js

例如0.000252 2.52e-4均值= 2.52×4=2.52×0.0001
