在php中将小数舍入到下一个数字

1.199 答案应该是 2. 1.99 也应该是 2.

这就是我发现的

echo(round(1.4,0,PHP_ROUND_HALF_UP) . "<br>");
echo(round(-1.4,0,PHP_ROUND_HALF_UP) . "<br>");
//Answer = 1
//Answer = -1

echo(round(1.4,0,PHP_ROUND_HALF_DOWN) . "<br>");
echo(round(-1.4,0,PHP_ROUND_HALF_DOWN) . "<br>");
//Answer = 1
//Answer = -1

echo(round(1.4,0,PHP_ROUND_HALF_EVEN) . "<br>");
echo(round(-1.4,0,PHP_ROUND_HALF_EVEN) . "<br>");
//Answer = 1
//Answer = -1

echo(round(1.4,0,PHP_ROUND_HALF_ODD) . "<br>");
echo(round(-1.,0,PHP_ROUND_HALF_ODD));
//Answer = 1
//Answer = -1
