[ Python ] 数字转字符串格式化问题, 不要科学记数法格式输出怎么搞

This topic created in 2961 days ago, the information mentioned may be changed or developed.

举几个例子
- 0.00000001000000000000 -> '0.00000001'
- 90000 -> '90000'
- 999999.000000001000 -> "999999.000000001"

尝试了 '%.f', 转成 decimal 再转字符串都不行, 总会搞成科学记数法输出有更好的方案吗

用正则表达式替换。

要指定截取的小数位数

print("%.8f" % 0.00000001000000000000)

print("%.9f" % 999999.000000001000)
