That's because the decimal part 0.5 is actually 1/2.
Each percentage point is roughly equivalent to one-tenth of one day.
Rounds 5.9 up, because the fraction part is greater than .5(6).
Compare: 13 cannot be represented precisely as a decimal fraction.当小数部分正好等于0.5时,CInt总是将其四舍五入成最接近该数的偶数。
When the fractional part is exactly 0.5, the CInt() function always rounds it to the nearest even number.Combinations with other parts of speech
如果没有小数部分,则只显示日期,例如4/3/93。
If there is no fractional part, display only a date, for example, 4/3/93.Float(点实数值):也叫浮点数,它们代表实数,并用小数点分割整数和小数部分。
Float(floating point real values): Also called floats, they represent real numbers andare written with a decimal point dividing the integer and fractional parts.数值必须至少为0,最多253-1,而且没有小数部分。
The value must be at least 0, at most 1014-1,and have no fractional part.如果我们再放一个点,那么JavaScript知道小数部分是空的,现在进入方法。
And if we place one more dot,then JavaScript knows that the decimal part is empty and now goes the method.Float(浮点实数值)-也称为浮点数,它们表示实数,并用小数点写成整数和小数部分。
Float(floating point real values): Also called floats, they represent real numbers andare written with a decimal point dividing the integer and fractional parts.以下计算时间自UNIX纪元秒(类似strftime('%s','now'),除了包括小数部分):.
Compute the time since the unix epoch in seconds(like strftime('%s','now')except includes fractional part).Float(浮点实数值)-也称为浮点数,它们表示实数,并用小数点写整数和小数部分。
Float(floating point real values): Also called floats, they represent real numbers andare written with a decimal point dividing the integer and fractional parts.如果相除的两个数都是整数的话,则结果也为整数,小数部分省略,如8/3=2;.
If the two numbers divided are integers,the result is also an integer, the fractional part is omitted, such as 8/3= 2;不过,这仅是14位小数;整数部分越大,表示小数部分的剩余位数就越少。
(This is only 14 decimals, however; the larger the integral part,the fewer bits remain to represent the fractional part.).
These functions cover all of the possible ways to deal with the decimal part of a number.小数部分0.1和0.2都不能精确地表示为二进制浮点数。
Neither of the decimal fractions 0.1 and 0.2 can be represented precisely as a binary floating point number.下面是计算从UNIX纪元算起的以秒为单位的时间(类似strftime('%s','now'),不同的是这里有包括小数部分):.
Compute the time since the unix epoch in seconds(like strftime('%s','now')except includes fractional part).其中xi是一个基本变量,xj是非基本变量。重写方程,使整数部分位于等号左边,小数部分位于等号右边:.
Where xi is a basic variable and the xj's are the nonbasic variables.Rewrite this equation so that the integer parts are on the left side and the fractional parts are on the right side.例如,DECIMAL(18,9)列在小数点的每一侧均有9位数字,因此,整数部分和小数部分均需要4字节。
For example, a DECIMAL(18,9) column has 9 digits on each side of the decimal point,so the integer part and the fractional part each require 4 bytes.计算以秒为单位的自unix纪元以来的时间(类似于strftime('%s','now'),但包括小数部分):.
Compute the time since the unix epoch in seconds(like strftime('%s','now')except includes fractional part).一个符号(看起来和英文句号一样),用来把整数部分(左边)和小数部分(右边)分开。
A symbol(looking exactly like a period)used to separate the whole number part(on the left) from the fractional part(on the right).
What about the remaining, smaller part?每当您需要某个值的小数部分时,我们可以把它分离出来。
Whenever you need a fractional amount of something, we will just separate it out.在圈数的许多,许多序列(视为实数的小数部分)是在这个意义上密集。
Many, many sequences of numbers in the circle(viewed as fractional parts of real numbers) are dense in this sense.
The majority of these law groups are small or….ParseInt仅能够返回整数,所以使用它会丢失小数部分。
ParseInt only returns whole numbers,so its use is diminished for decimals.整数是正数,没有小数部分或小数点,因为它们代表没有碎片或碎片的整个物体。
Whole numbers are positive numbers which have no fractional parts nor decimal points as they represent whole objects without fragments or pieces.小数位是指数字的小数部分的位数,它不可以是负数,也不能大于精度。
The scale, which is the numbers to the right of the decimal point, cannot be negative or greater than the precision.
