bcdiv — Divide two arbitrary precision numbers
Divides the left_operand by the right_operand.
The left operand, as a string.
The right operand, as a string.
此可选参数用于设置结果中小数点后的小数位数。 也可通过使用 bcscale() 来设置全局默认的小数位数，用于所有函数。
Returns the result of the division as a string, or NULL if right_operand is 0.

echo bcdiv('105', '6.55957', 3); // 16.007
