Number

Constructs a BigNumber object from a string, integer, float, or any object that may be cast to a string, resulting in a numeric string value

Returns the string value of this BigNumber

将当前数字设置为自身的绝对值 Sets the current number to the absolute value of itself

加法运算 Adds the given number to the current number

通过重新排列当前数字来查找下一个最高整型值 Finds the next highest integer value by rounding up the current number if necessary

比较数据 Compares the current number with the given number

Returns 0 if the two operands are equal, 1 if the current number is larger than the given number, -1 otherwise.

进制转换, 转换成任意进制 Returns the current value converted to an arbitrary base

将当前数字的值减一 Decreases the value of the current number by one

除法运算 Divides the current number by the given number

通过舍入当前数字找到下一个最低整数值 Finds the next lowest integer value by rounding down the current number if necessary

返回小数位数 Returns the scale used for this BigNumber

If no scale was set, this will default to the value of bcmath.scale in php.ini.

获取字串值 Returns the current raw value of this BigNumber

增加 Increases the value of the current number by one

检测是否相等 Returns true if the current number equals the given number

检测是否大于 Returns true if the current number is greater than the given number

检测大于等于 Returns true if the current number is greater than or equal to the given number

检测小与 Returns true if the current number is less than the given number

检测小与等于 Returns true if the current number is less than or equal to the given number

是否是负数 Returns true if the current number is a negative number

是否是正数 Returns true if the current number is a positive number

取余数 Finds the modulus of the current number divided by the given number

乘法 Multiplies the current number by the given number

返回负数 Sets the current number to the negative value of itself

幂运算 Raises current number to the given number

指定次数的幂运算 Raises the current number to the $pow, then divides by the $mod to find the modulus

This is functionally equivalent to the following code:

    $n = new BigNumber(1234);
    $n->mod($n->pow(32), 2);

However, it uses bcpowmod(), so it is faster and can accept larger parameters.

四舍五入 Rounds the current number to the nearest integer

设置小数位数 Sets the scale of this BigNumber

设置为一个新值 Sets the value of this BigNumber to a new value

位向左移动 Shifts the current number $bits to the left

位向右移动 Shifts the current number $bits to the right

前数字的符号 Returns the sign (signum) of the current number

求平方根 Finds the square root of the current number

减法 Subtracts the given number from the current number

进制转换 Converts a number between arbitrary bases (from 2 to 36)

转换 10 进制到其他进制 Converts a base-10 number to an arbitrary base (from 2 to 36)

转换成 10 进制 Converts a number from an arbitrary base (from 2 to 36) to base 10

设置默认小数位数 Changes the default scale used by all Binary Calculator functions

转换成 String 类型 Filters a number, converting it to a string value
