JS取整 1.toFixed(num)(ps:num为保留小数点后几位) 自定义保留小数点后几位,进行四舍五入.严格来说,这个函数不属于取整,但是当num=0时,也就是取整了,所以一起放到这里,方便查找. 栗子: var num = 5.2369; num .toFixed(0) = 5; num .toFixed(1) = 5.2; num .toFixed(2) = 5.24; num .toFixed(3) = 5.237; 2.Math.ceil(num) //返回大于等于其数值参数的最
If IsNull({DECL_INV_ITEM_I.DECLEAR_NO}) Or Trim({DECL_INV_ITEM_I.DECLEAR_NO}) = "" Then "0" Else CStr({DECL_INV_ITEM_I.EX_RATE},5,',') CSTR({number_field}, 0, ''),第一个是数字字段:第二个是保留的小数位,0是整数:第三个是千分位分隔字符.
