[metapost] Change in behavior of booleans with numbersystem=decimal

Dear Metapostals:

I don't know whether --numbersystem=decimal is considered

ready to use, but I have observed some odd behavior for the

following file:


show known (0,0,.5,.5);

show cmykcolor (0,0,.5,.5);


The command

    mpost test

returns true and true, but the command

    mpost --numbersystem=decimal test

returns false and false. This is causing mfpic to fail when

the decimal numbersystem is used.

The fact that these are cmykcolor values seems to be irrelevant.

I get similar behavior with pairs and paths. The boolean

"known X" simply seems to not work. Also the booleans

"cmykcolor X", "pair X" and "path X" (those are the only

ones I've tried so far).

I'm using MetaPost, version 1.999 (TeX Live 2015/W32TeX)

under windows 7.
