Returns the difference between two complex numbers.
Sample Usage
IMSUB("6+5i", "2+3i")
Syntax
IMSUB(first_number, second_number)
first_number- The complex number to subtractsecond_numberfrom.second_number- The complex number to subtract fromfirst_number.
Notes
- The difference between two complex numbers is defined as follows:
- (a+bi) - (c+di) = (a-c) + (b-d)i
- You can subtract two complex numbers only if they have the same suffix (i or j). For example, you can't do
IMSUB("4+3i", "1+2j").
