Allow for leading with a decimal point

[elemonader]

Highly underrated app, IMO. Thank you, first and foremost.

Suggestion:
Eliminate the required, leading numeral and allow a typed equation to start with a decimal.

For example:
0.15 + .25 ...works fine.
.15 + .25 ...does not. The app will not allow the decimal point typed first.

This is seemingly of small importance, I know. But perhaps it would be just as trivial a fix? I use the app for dozens of BTC calculations on a daily basis and most of my equations start with fractions.
