Error with \pdf@elapsedtime (LuaTeX) : math.floor or related is required

[FOCCOF]

Problem : \pdf@elapsedtime defined for LuaTeX (in pdftexcmds.lua) says at the end :+1:

tex.write(string.format("%d", val))

while it should probably say :+1:

tex.write(string.format("%d", math.floor(val)))

Because `val' is not an integer but a float, which has to be truncated before printing.

Thanks for the report, the test file was Ok as recently as texlive 2018. I assume this is Lua 5.3 introducing the integer type that has broken it, we'll fix.

@davidcarlisle I added the math.floor and will upload to ctan.

Funny, we already had this in l3luatex!

fix has been sent to ctan.
