Checkpoint 5.9 - Mobile-PDA
Where possible, decimals are used instead of fractions
WCAG 1.0 Priority 1
WCAG Guideline 14. Ensure that documents are clear and simple.
Mobile devices are constrained by the size of the screen and the content authors need to use this space efficiently. Fractions are typically displayed using smaller, superscripted and subscripted numbers and their small size can be difficult to see on such a small screen, especially as the environment that the screen is being used in can often be less than optimal for viewing a screen.
Requirement
Where possible, decimals are used instead of fractions
Recommendation
All decimals less than 1 need to begin with the number 0 prior to the decimal point. Take into account the number of digits following the decimal point to present the right information but without putting too many digits on the screen.
Checking Tool
View the page on a mobile device and look for the display of any fractions. Consider whether these could be replaced with decimal equivalents without loss of any specific information for the user.
