#8896: 0.0000000000000000000000000000 is parsed completely differently than
1.0000000000000000000000000000 for no good reason

> Truncation only makes sense from the right; and you don't express
precision by padding zeros to the left. Stating that the earth's diameter
is about 013 million meters doesn't give more information than stating it
is about 13 million meters.
Which has the same information as saying the Earth's diameter is about
0.000013 trillion meters. Whether or not a digit is significant is not a
function of whether it is on the left or right of the decimal.
Would you then say that {{{0.00e9}}} and {{{00.0e8}}} and {{{.000e10}}}
have different precisions?
