将float转换为整数时，php出错

Question

当我从一个浮点数转换为整数时，它表现得很奇怪并且没有预期的结果

<?php
$amount = str_replace(",", "", '1,051.36') * 100; //105136
$number = (int)$amount; //105135

Answer 1

您可以使用 round（），floor（）或 ceil（）函数将浮动金额舍入到最接近的整数。

// round to next highest Int 
$number_ceiled = ceil($amount); //105136

// round to next lowest Int 
$number_floored = floor($amount); //105135

// can do both and round to the much closed 
$number_rounded = round($amount); //105136

return (int)$number_rounded; //105136

在你的情况下考虑特别是round（）。
