Biggest Number in Excel
Can someone tell us what is the biggest number in Excel? I have read some articles about this topic, some people say that this number is the biggest: 9.99999999999999E+307
As per https://support.microsoft.com/en-us/office/excel-specifications-and-limits-1672b34d-7043-467e-8e27-269d656771c3, the largest number is indeed 9.99999999999999E+307 when you enter the number in a cell manually. But within formula calculations largest number is 1.7976931348623158e+308. But you can't enter a number larger than 9.99999999999999E+307.
