In addition, the result of a `BigDecimal` or `BigInteger` power operation within a SpEL
expression cannot exceed 1,000,000 bits by default – approximately equivalent to a
decimal number with 300,000 digits. Power operations involving large base values or large
exponents can be computationally expensive, and this limit ensures that evaluations
remain bounded; however, the `maximumBigPowerBits` value is configurable. If you create a
`SpelExpressionParser` programmatically (the recommended approach), you can specify a
custom `maximumBigPowerBits` value when creating the `SpelParserConfiguration` that you
provide to the `SpelExpressionParser`. To remove this limit entirely, pass
`Integer.MAX_VALUE` as the `maximumBigPowerBits` value. If you are not able to configure
an explicit value for `maximumBigPowerBits` via `SpelParserConfiguration`, you can set a
JVM system property or Spring property named `spring.expression.maxBigPowerBits` to the
maximum result size in bits (see xref:appendix.adoc#appendix-spring-properties[Supported
Spring Properties]).
