In 208 I'd like us 1) clarify 2) to add a little feature.
Feature: Although we agreed not to have decimal points in the expression,
I'd like to introduce them.. but with a specific semantics..
The last digit in scientific notation is typically used to present
an "estimation". I think I would like this "feature" but since we do not
want to force the use of a estimated digit I think its best as a decimal
point, viz. all digits after the decimal point are estimations below the
precision of measurement.
1) The character '.' is used to mark the start of estimation
2) The precision is described by the exponent
y17e7 is the year 170000000 with precision of 10000000 years
y17.3 is the year 173000000 with precision 10000000, e.g. 3000000 is an
y17.33 is the year 173300000 with precision 10000000, e.g. 3300000 is an
The three dates above all have the same precision but different sub-
