Introduction

In this page you can find the example usage for org.apache.commons.lang.math NumberUtils toDouble.

Prototype

public static double toDouble(String str)

Document

Convert a String to a double, returning 0.0d if the conversion fails.

If the string str is null, 0.0d is returned.

 NumberUtils.toDouble(null)   = 0.0d NumberUtils.toDouble("")     = 0.0d NumberUtils.toDouble("1.5")  = 1.5d
