iOS小数取整的方法(ceil floor round)示例
<h2>iOS小数取整的方法</h2><p>ceil(value)：求大于小数value的最小整数。</p>
<p>floor(value)：求小于小数value的最大整数。</p>
<p>round(value)：小数value的四舍五入取整。</p>
<p>示例（一）：</p>
<div class="jb51code"><pre class="brush:cpp;">CGFloat width = 70.15;
;</pre></div>
<p>打印：</p>
<blockquote><p> ceil(a) = 71.000000<br /> floor(a) = 70.000000<br /> round(a) = 70.000000</p></blockquote>
<p>示例（二）：</p>
<div class="jb51code"><pre class="brush:cpp;">width = 70.77;
;</pre></div>
<p>打印：</p>
<blockquote><p> ceil(a) = 71.000000<br /> floor(a) = 70.000000<br /> round(a) = 71.000000</p></blockquote>
<div class="jb51code"><pre class="brush:cpp;">- (void)logCeilFoorRoundWithValue:(CGFloat)value {
NSLog(@"ceil(a) = %f", ceil(value));
NSLog(@"floor(a) = %f", floor(value));
NSLog(@"round(a) = %f", round(value));
}</pre></div>
