Or you can use %f, but then large numbers yield long strings of digits rather than the scientific notation you'd prefer. As a parting gift, here's a routine that prints real numbers a little more nicely, automatically adjusting format codes depending on what kind of number you give it. ...

浮点常量也可以用科学记数法(scientific notation)表示。数值1.7e4就是用这种表示法表示的浮点数,表示1.7×。字母e前面的值称为尾数(mantissa),后面的值称为指数(exponent)。指数表示10的幂,且该指数前面可以有一个可选的加号或减号,尾数将与这个幂值相乘。因此,在常数2.25e−3中,2.25是尾数的值,−3是指...

How do I use mantissa and exponential representation, or scientific representation, if I use floating point types in C programming? (如果在 C 语言编程中使用浮点类型,如何使用尾数和指数表示法或科学表示法?) In C programming, when dealing with floating point types (float, double, and long double)...
