Why do ingredient amounts show as decimals while I’m editing?
Quick answer: Edit mode always stores numbers as decimals so CookBook can do fast math for scaling and conversions. Once you tap Save, the recipe switches back to your preferred display - fractions or decimals, based on the setting you chose in Settings → Conversions → Quantity display.
What’s happening under the hood
CookBook converts every fraction (e.g., ¾ cup) to a decimal (0.75) so it can handle serving-size scaling and conversions.
After you save, CookBook formats the number shown to the style selected in Settings.
How to change your preferred format
- Tap Side menu ☰ → Settings.
- Under Conversions → Quantity display choose Fractions or Decimals.
- Return to any saved recipe - amounts now display in the style you picked.
