浮点数小数 的6种舍入方式 在计算机中,浮点数表示实数的近似值。由于浮点数的位数是有限的,因此在计算机中进行浮点数运算时,必须对浮点数进行舍入。以下是四种常用的浮点数舍入方式: 向零舍入 round towards zero (round down) 向零舍入是指直接截去小数点后的数字,不进行四舍五入。例如,对于3.1415926,向零舍...
matlab里面的取整函数(fix,round,floor……,在对数据进行处理时,有时我们需要对含有小数的数据进行取整处理,本例分享matla里面常用的几种取整函数,fix、roud、floor、ceil

fixRound towards zero. fix(X) rounds the elements of X to the nearest integers towards zero. 例: t = 7.6806 3.5388 3.6130 2.3309 3.4719 7.4163 5.8736 2.5372 7.0590 fix(t) ans = 7 3 3 2 3 7 5 2 7 round - 向最近的方向取整,亦即“四舍五入” roundrounds towards nearest decimal or in...

The most common ones are: Round to nearest q is the integer that is closest to y (see "Round away from zero" for tie-breaking rules). Round towards zero(or truncate) q is the integer part of y, without its fraction digits.
Floating-point to integer implicit casts and conversions, which always round towards zero. The results of floating-point arithmetic operators in constant expressions, which always round to the nearest value. To use these functions, you must turn off floating-point optimizations that could prevent acce...
If number is negative and significance is positive, the value is rounded up, towards zero, as in row 6. If number and significance are negative, the value is rounded down, as in row 8. Excel INT function The INT function rounds a number down to the nearest integer. ...
