                  问题描述

                  我有一个指数格式的浮点数,即 4.1595246940817E-17,我想将其转换为十进制数,如 2.99 等.

                  I have a floating point number in exponential format i.e. 4.1595246940817E-17 and I want to convert it into decimal number like 2.99 etc.

                  任何帮助将不胜感激.

                  format_number() sprintf() 似乎对我不起作用.

                  format_number() sprintf() don't seem to be working for me.

                  推荐答案

                  你需要一个更好的数学扩展,比如 BC Math, GMP... 来处理更精确的精度.
