So you want to translate SI unit abbreviations (‘K’,’M’,…) into exponents, and thus numerical powers-of-ten. Given that all units are single-letter, and the exponents are uniformly-spaced powers of 10**3, here’s working code that handles ‘Kilo’…’Yotta’, and any future exponents: > 10 ** (3*as.integer(regexpr(‘T’, ‘KMGTPEY’))) [1] 1e+12 Then just multiply that power-of-ten by the decimal value … Read more
It is useful when you want to size something in relation to the height of your text’s lowercase letters. For example, imagine working on a design like so: In the typographic dimension of design, the height of letters has important spatial relationships to the rest of the elements. The lines in the source image above … Read more
It uses pixels, but I’m sure you’re wondering how to use dips instead. The answer is in TypedValue.applyDimension(). Here’s an example of how to convert dips to px in code: // Converts 14 dip into its equivalent px Resources r = getResources(); int px = Math.round(TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, 14,r.getDisplayMetrics()));
TL;DR: use px. The Facts First, it’s extremely important to know that per spec, the CSS px unit does not equal one physical display pixel. This has always been true – even in the 1996 CSS 1 spec. CSS defines the reference pixel, which measures the size of a pixel on a 96 dpi display. … Read more
