In fact, if PCalc had only the LCD segment font, I would never use it. PCalc has two fonts for the display: a retro font that mimics the old LCD-segment displays and a solid font with rounded numerals.Īs you might guess from the earlier screenshots, I much prefer the easier-to-read font. The next rounded rectangle contains the aesthetic settings for the number display. PCalc doesn’t let you create your own themes or layouts you’ll just have to live with one of the 24 vertical and 30 horizontal combinations. I’m torn between the Default and Mirror horizontal layouts-Default puts the number keys closer to my right hand, but there’s something about Mirror that looks better to me. I use the Primary Colors theme (the theme I’ve used to show all the layouts) and the Retro vertical layout. PCalc has four portrait layouts: Basic, Classic PCalc, Default, and Retro:Īnd five horizontal layouts: Classic PCalc, Default, Mirror, Retro Hex, and Retro Scientific: Seventy Three has a more rounded key shape in addition to its own color scheme. Themes are basically color schemes, and PCalc has six of them.įrom left to right and top to bottom, the themes are A Touch Of Color, Blue Sun, High Power, Primary Colors, Rough Draft, and Seventy Three. The next rounded rectangle lets you choose the theme and layout of your calculator. The thousands-separating comma in the Normal display is a setting we’ll get to in a bit. In Scientific, there’s always one digit to the left of the decimal point in Engineering, the exponent is always a multiple of 3. The little numbers in the Scientific and Engineering displays represent the exponents in the expressions 2.49000×10 4 and 24.9000×10 3, respectively. The Normal, Scientific, and Engineering displays of this number would be as follows: The equatorial circumference of the Earth is 24,900 miles. The difference between “Normal,” “Scientific,” and “Engineering” is best shown with an example. If you have the iPhone upright, you’ll see the digits in the display get smaller as you slide the control farther to the right. The slider controls the number of decimal places and the checkbox controls whether a number like 5.375 is displayed as 5.375 or 5.37500. These are what I consider to be the structural settings for the number display-how many digits are shown and how they’re arranged. The first group of appearance settings is in the second rounded rectangle. Changes you make to the settings are immediately visible in the display, which means you usually don’t have to keep going back and forth between the settings and the calculator to see the effect of your changes. When you’re fiddling with the settings, the calculator display is actually always visible at the bottom of the iPhone screen 1, and the list of settings scrolls behind it. (I should mention here that although the screenshot above shows the calculator display at the bottom of the list of settings, that’s not how it looks on the phone. Related settings are grouped in the white rounded rectangles. In this post, we’ll focus on the settings that control the way PCalc looks. Like a Dashboard widget, PCalc has an icon with a circled i which, when pressed, shows you its configuration options. This one describes PCalc’s various “looks” and how you can, within limits, customize its appearance to fit your taste and needs. The first post covered, in brief, my reasons for using PCalc instead of the iPhone’s built-in calculator. This is the second in my Definitive Series of Posts on PCalc for the iPhone.
