[Bug]: copy+pasting a formula that includes number in exponential format fails with the error "There is no AST with such key in the cache"

[Andrew-Bx]

Description

Attempting to copy+paste a formula that includes exponential notation (e.g. "=1.25e+5") results in the error:
There is no AST with such key in the cache

code to reproduce:

import HyperFormula from 'hyperformula';

const hf = HyperFormula.buildEmpty({
  licenseKey: 'gpl-v3',
});

const sheetName = hf.addSheet('main');
const sheetId = hf.getSheetId(sheetName);

// Arrange data

const tableData = [['100000', '1.25e+5', '=100000', '=1.25e+5']];

hf.setCellContents(
  {
    row: 0,
    col: 0,
    sheet: sheetId,
  },
  tableData
);

// Act - copying the first three columns works fine:

hf.copy({
  start: { sheet: sheetId, col: 0, row: 0 },
  end: { sheet: sheetId, col: 2, row: 0 },
});
hf.paste({ sheet: sheetId, col: 0, row: 1 });

const row1Values = hf.getRangeValues({
  start: { sheet: sheetId, col: 0, row: 1 },
  end: { sheet: sheetId, col: 2, row: 1 },
});
console.log({ row1Values }); // as expected, values are: [100000, 125000, 100000]

// Act - copying the last column gives the error:

hf.copy({
  start: { sheet: sheetId, col: 3, row: 0 },
  end: { sheet: sheetId, col: 3, row: 0 },
});
hf.paste({ sheet: sheetId, col: 3, row: 1 }); // results in: Error: There is no AST with such key in the cache

Hi @Andrew-Bx

Thank you for reporting this. We can confirm that exponential numbers are sometimes not handled correctly, so this is a bug.
