The long type modifier can also be used withdoublevariables. // large floating-point numberlongdoublec =0.333333333333333333L; Note:To indicatelong double, we use theLsuffix. If we do not use the suffixL, it's adoublevalue that is converted tolong double(which may result in data loss). ...
在大多数情况下,这不是问题,因为long double通常用于最大程度地减少中间计算中的错误,然后将结果截断为double。 long double的各种C实现可能具有不同的范围和精度。sizeof提示使用基础浮点符号,但未指定。long double不需要具有33到36个小数。它甚至可以具有与double完全相同的表示形式。 如果不对精度进行硬编码,但要...
