Hi,

I've checked in 2 changes to the floating point comparison tools.

1. BOOST_CHECK_CLOSE now can compare values of different types:

BOOST_CHECK_CLOSE( 2, 2.1, 6 ); // compare and and double BOOST_CHECK_CLOSE( 2.1, 2, 6 ); // compare double and int BOOST_CHECK_CLOSE( 2.1, 2.f, 6 ); // compare double and float

2. Floating point comparison tools now report difference if any:

BOOST_CHECK_CLOSE( 2, 2.1, 3 ) will lead to:

difference{4.7619%} between 2{2} and 2.1{2.1} exceeds 3%

BOOST_CHECK_CLOSE_FRACTION( 2, 2.1, 0.04 ) will lead to:

difference{0.047619} between 2{2} and 2.1{2.1} exceeds 0.04

Any comments appreciated,

Yeh! Thanks Gennadiy, that'll be a big help, John.
