在同一个月，epsilon-1号火箭首次发射，搭载一个识别大气相互作用的光谱地球观测站sprint-a探测器；在11月，日本一名宇航员将开始长期留在国际空间站充当探险指挥官。
in that same month, the maiden flight of the epsilon-1 rocket had launched the sprint-a probe, a spectroscopic planet observatory for recognition of interaction of atmosphere; and in november a japanese astronaut would begin his long-term stay on the international space station as expedition commander.
eps () 函数返回机器的 epsilon 值： 它是 1 和下一个比它大点数之间的差值。 由于计算机使用有限位数的数字， 舍入误差在所有计算中都是不可避免的( 尽管通常不太严重) 。
eps() returns the machine epsilon; this is the difference between 1 and the next largest floating-point number. because computers use a finite number of digits, roundoff error is inherent (but usually insignificant) in all calculations.
