FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date.

Fauna accounts created after August 21, 2024 must use FQL v10. These accounts will not be able to run FQL v4 queries or access the v4 Dashboard.

For more details, see the v4 EOL announcement and migration guide. Contact support@fauna.com with any questions.

Parameters

Parameter Type Definition and Requirements

value

Number

The power to raise e to.

Returns

A number which is the result of raising e to a power.

Examples

The query in the following example returns the Euler’s number raised to the power of 1.5.

client.query(
  q.Exp(1.5)
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
4.4816890703380645
result = client.query(
  q.exp(1.5)
)
print(result)
4.4816890703380645
result, err := client.Query(
	f.Exp(1.5))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}

try
{
    Value result = await client.Query(
        Exp(1.5)
