Why does the statement lt(0.24 - 0.22, 0.02) return 1?

lt(0.02,0.02) returns 1 also...

Welcome to floating point arithmetic.
Every new boy makes this "discovery" and makes a fool of himself by
posting to CSSM.
Have a look here:

Really? Try it again ... *exactly* as you have typed it.

If "lt(0.02, 0.02)" really replies 1, I assume, that you have created a function called "lt", which shadows Matlab's toolbox function LT.
Please try this to find all instances of function called "lt":
which('lt', '-all')

Good luck, Jan
