本文整理了Java中com.fasterxml.jackson.databind.JsonNode.decimalValue()方法的一些代码示例，展示了JsonNode.decimalValue()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。JsonNode.decimalValue()方法的具体详情如下：
包路径：com.fasterxml.jackson.databind.JsonNode
类名称：JsonNode
方法名：decimalValue

JsonNode.decimalValue介绍

[英]Returns floating point value for this node (as BigDecimal), if and only if this node is numeric ( #isNumber returns true). For other types returns BigDecimal.ZERO.
[中]返回此节点的浮点值（作为BigDecimal），当且仅当此节点为数字（#isNumber返回true）。对于其他类型，返回BigDecimal.ZERO。

代码示例

/**
 * Converts the lhs and rhs JsonNodes to the numeric values
 * and delegates to the matches method that operates on the
 * numeric values alone.
 *
 * @param lhs Lhs expression
 * @param rhs Rhs expression
 * @return Boolean result of the matches method of the
 * corresponding comparison operator
 */
@Override
public final boolean matches(JsonNode lhs, JsonNode rhs) {
  return matches(lhs.decimalValue(), rhs.decimalValue());
}
