本文整理了Java中com.fasterxml.jackson.databind.JsonNode.floatValue()方法的一些代码示例，展示了JsonNode.floatValue()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.floatValue()方法的具体详情如下：
包路径：com.fasterxml.jackson.databind.JsonNode
类名称：JsonNode
方法名：floatValue

JsonNode.floatValue介绍

[英]Returns 32-bit floating value for this node, if and only if this node is numeric ( #isNumber returns true). For other types returns 0.0. For integer values, conversion is done using coercion; this means that an overflow is possible for long values
[中]返回此节点的32位浮点值，当且仅当此节点为数字时（#isNumber返回true）。对于其他类型，返回0.0。对于整数值，使用强制进行转换；这意味着“long”值可能会溢出
