EXP Function

Returns e raised to a power.

✓ Excel✓ Google SheetsExcel All versions

Syntax

EXP
(number)

Parameters

ParameterDescriptionRequired
numberThe exponent to which e is raised.Required

Basic Example

e raised to the power of 1

=EXP(1)
Result2.718281828

e¹ equals the constant e, about 2.71828.

Advanced Examples

Example 1: e squared

Compound growth base.

Raise e to 2.

=EXP(2)
Result: 7.389056099
e² ≈ 7.38906.

Example 2: Inverse relationship with LN

Verify the log identity.

LN and EXP cancel each other.

=LN(EXP(3))
Result: 3
Taking the natural log of e³ returns 3.

How EXP Works

EXP computes e^number, where e ≈ 2.71828182845904. It is the inverse of LN: LN(EXP(x)) = x and EXP(LN(x)) = x (for x > 0).

Important Notes & Limitations

  • Very large exponents overflow to #NUM! (e.g. EXP(710) and above).

  • Results are floating-point approximations of e.

  • EXP only computes powers of e; use POWER for other bases.

Common Errors & Fixes

#NUM!The exponent is too large, causing overflow.

Fix: Use a smaller exponent or scale the calculation.

#VALUE!Non-numeric argument.

Fix: Supply a numeric exponent.

Frequently Asked Questions

What is e?
e is Euler's number, approximately 2.71828182845904, the base of natural logarithms.
How do I raise other numbers to a power?
Use POWER(base, exponent) or the ^ operator; EXP only raises e.
Why does EXP(LN(x)) equal x?
EXP and LN are inverse functions, so they cancel each other for positive x.
