1. Is it possible to input mathematical constants in cell/s using
functions in Excel ?.

For example : PI, e, Pythagoras constant, Omega Constant, Ramanujan - Soldner constant, Golden Ratio, Legendre's constant etc ?.

2. Will it be useful to create functions for inputting mathematical constants in excel spreadsheets (if not available) ?.

Awaiting your reply,

Thanks & Regards,
Prashant S Akerkar

Answer
Prashant:

Excel does have some mathematical constants available.  Here are some examples:

Pi; 3.141592654
=PI()

E; 2.718281828
=EXP(1)

Pythagoras Constant; 1.414213562
=SQRT(2)

If a particular constant is not predefined in Excel then you can create a named reference that equals the approximate value of that constant.

For example,

1) Select formulas -> name manager
2) Type Omega in the name field
3) In the refers to type =0.5671432904097838729999686622

You have now defined Omega within Excel and can use it in a formula.

For example,

Enter the following into cell A1...
=omega+2

The result will be 2.56714329
