Divides num1 by num2.

Parameters

num1

The dividend, as a string.

num2

The divisor, as a string.

Errors/Exceptions

This function throws a ValueError in the following cases:

  • num1 or num2 is not a well-formed BCMath numeric string.
  • scale is outside the valid range.

This function throws a DivisionByZeroError exception if num2 is 0.
