米转为码或者英里

当距离小于1999yd时不显示小数点

当距离大于1999yd小于199.9mi时候需要显示小数点

当距离大于199.9mi小于1999mi的时候不显示小数点

当距离超过1999mi的时候都显示成1999mi。



内涵注释非常清楚





1999码 = 1 827.8856 米

199.9英里 = 321 699.07 米





说明：



第五位显示0表示单位是yd没有小数点

第五位显示1表示单位为mi有小数点

第五位显示2表示单位为mi没有小数点



注：第五位为标志位，非数值位。在主函数中可以根据这位来判断单位和要不要显示小数点。-Public Inch conversion meters to yards, or miles when the distance is less than 1999yd not displayed when smaller than the decimal point when the distance of more than 1999yd the time required to display a decimal point when the 199.9mi distance of more than 199.9mi when less than 1999mi not show the decimal point when the distance of more than 1999mi at all times displayed as 1999mi. Note very clear connotation of 1999 yards = 1 827.8856 meters 199.9 miles = 321 699.07 meters Descr iption: The fifth unit is yd show 0 that there is no decimal point, said a fifth digital display unit is the fifth decimal point mi have shown that two units do not mi decimal Note: The fifth place for the flag, non-numeric bit. In the main function can be judged according to the units and whether or not to display a decimal point.
