The log10() function returns the base 10 logarithm of a number.Tip: The base 10 logarithm indicates approximately how many digits the integer part of a number has. See how to use it to count digits in the example below.The log10() function is defined in the <cmath> header file....

In BaseGlyphRecord and LayerRecord, changed field names “gID” to “glyphId”. Changed general requirement regarding glyph ID 1 to a compatibility note. cpal.htm Changed field names: “offsetFirstColorRecord” to “colorRecordsArrayOffset” “offsetPaletteTypeArray” to “paletteTypesArrayOffset”...
10.支持日志压缩,压缩为zip或7z等文件,缩小体积,便于储存和通过网络传输。 日志的意义在于排查问题和运维。 若所有机器都把日志上传上去则失去了意义,且服务器也顶不住。而这种被动的触发,针对某个机器的上送是可行的且有价值的。并且还可以在应用中增加当应用出现客户没发现缺不该出现的问题时,主动触发上报异常日...
