[LTP] Test case float_trigo Reading dsin error

[fixed-term.Islam.Tammam]

Hi Cyril,
what is the format of dsin and dtan files ? i.e how do they look like 
since they are binaries i have no clue for creating them.

i just had a look at the link here
https://github.com/linux-test-project/ltp/tree/master/testcases/misc/math/float/trigo

to be able to generate the data files "manually" , but such data files 
shall be generated automatically when running the ./float_trigo test 
cases itself. do you have an idea how so that happens ? and what is the 
destination directory of the generated files , since i checked 
/opt/ltp/testcases/bin but didn't find any data files generated there.



Best regards,
