[lmi-commits] [lmi] master 43bbe463 05/11: Use lmi::expm1() and lmi::log1p() in a unit-test function

[Greg Chicares]

branch: master
commit 43bbe46333849a2dcbf61a580c8e07fba1d6ad81
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Use lmi::expm1() and lmi::log1p() in a unit-test function
    
    Production uses 'double' expm1() and log1p(), rather than 'long double'
    as the comment previously said.
