PHP | bcdiv() Function

The bcdiv() function in PHP is an inbuilt function and is used to divide two arbitrary precision numbers. This function accepts two arbitrary precision numbers as strings and returns the division of the two numbers after scaling the result to a specified precision.

Syntax:

string bcdiv ( $num_str1, $num_str2, $scaleVal)

Parameters: This function accepts three parameters as shown in the above syntax and explained below:

• $num_str1: This parameter is of string type and represents the dividend. This parameter is mandatory.
• $num_str2: This parameter is of string type and represents the divisor. This parameter is mandatory.
• $scaleVal: This parameter is of int type and is optional. This parameter tells the number of digits that will appear after the decimal in the result of division. It’s default value is zero.

Return Value: This function returns the division of the number $num_str1 by $num_str2 as string.

Examples:

Input:  $num_str1 = 11.222, $num_str2 = 3
Output: 3
Since the parameter $scaleVal is not specified so
no digits after decimal is appeared in the 
result after division.

Input:  $num_str1 = 11.222, $num_str2 = 3, $scaleVal = 4
Output: 3.7406
