string to floating point number.<p>This function converts the initial portion of the string pointed to by nptr to double floating point representation. The behaviour is the same as<p>CPLStrtod(nptr, (char **)NULL);<p>This function does the same as standard atof(3), but does not take locale in account. That means, the decimal delimiter is always '.' (decimal point). Use <a class="el" href="cpl__conv_8h.html#0a01ca071035c36d4b4f85336e08c5d5">CPLAtofDelim()</a> function if you want to specify custom delimiter.<p>IMPORTANT NOTE. Existance of this function does not mean you should always use it. Sometimes you should use standard locale aware atof(3) and its family. When you need to process the user's input (for example, command line parameters) use atof(3), because user works in localized environment and her input will be done accordingly the locale set. In particular that means we should not make assumptions about character used as decimal delimiter, it can be either "." or ",". But when you are parsing some ASCII file in predefined format, you most likely need <a class="el" href="cpl__conv_8h.html#fb5bf88066f997b1ab3b3911f5e9b722">CPLAtof()</a>, because such files distributed across the systems with different locales and floating point representation shoudl be considered as a part of file format. If the format uses "." as a delimiter the same character must be used when parsing number regardless of actual locale setting.<p><dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td valign="top"></td><td valign="top"><em>nptr</em> </td><td>Pointer to string to convert.</td></tr> </table></dl><dl class="return" compact><dt><b>Returns:</b></dt><dd>Converted value, if any. </dd></dl>⌨️ 快捷键说明
