\ There are a few things to be noted:
-\ - Following the despicable practice of the original, this version
-\ sets the base to HEX for everything that gets loaded later.
-\ Floating-point input is ambiguous when the base is not decimal, so
-\ you have to set it to decimal yourself when you want to deal with
-\ decimal numbers.
+\ - Loading ttester.fs does not change BASE. Loading tester.fs
+\ changes BASE to HEX (like the original tester). Floating-point
+\ input is ambiguous when the base is not decimal, so you have to set
+\ it to decimal yourself when you want to deal with decimal numbers.
\ - For FP it is often useful to use approximate equality for checking
\ the results. You can turn on approximate matching with SET-NEAR
