Interface EQN_Fraction

Equation fraction options

A fraction has a numerator and denominator separated by a vinculum symbol EQN_VinculumSymbol.

Options can be an object, or an array in the property order below

To test examples, append them to the boilerplate

Example

// Simple
figure.add({
  name: 'eqn',
  make: 'equation',
  forms: {
    1: { frac: ['a', 'vinculum', 'b'] },
  },
});
figure.elements._eqn.showForm('1');

Example

// Example showing object and array fraction definitions, and nesting
figure.add({
  name: 'eqn',
  make: 'equation',
  elements: {
    v1: { symbol: 'vinculum' },
    v2: { symbol: 'vinculum' },
    plus: '  +  ',
  },
  forms: {
    // Fraction object form
    1: {
      frac: {
        numerator: 'a',
        denominator: 'b',
        symbol: 'v1',
      },
    },
    // Fraction array form
    2: { frac: ['a', 'v1', 'd'] },
    // Nested
    3: {
      frac: {
        numerator: [{ frac: ['a', 'v1', 'd', 0.7] }, 'plus', '_1'],
        symbol: 'v2',
        denominator: 'b',
      }
    },
  },
  formSeries: ['1', '2', '3'],
});
const eqn = figure.elements._eqn;
eqn.onClick = () => eqn.nextForm();
eqn.setTouchable();
eqn.showForm('1');

Example

// Create equation object then add to figure
const eqn = figure.collections.equation({
  elements: {
      v1: { symbol: 'vinculum' },
      v2: { symbol: 'vinculum' },
      plus: '  +  ',
    },
    forms: {
      1: {
        frac: {
          numerator: 'a',
          denominator: 'b',
          symbol: 'v1',
        },
      },
      2: { frac: ['a', 'v1', 'd'] },
      3: {
        frac: {
          numerator: [{ frac: ['a', 'v1', 'd', 0.7] }, 'plus', '_1'],
          symbol: 'v2',
          denominator: 'b',
        }
      },
    },
    formSeries: ['1', '2', '3'],
});
figure.add('eqn', eqn);
eqn.onClick = () => eqn.nextForm();
eqn.setTouchable();
eqn.showForm('1');
