Assume I want to setup a formula for a cell which should calculate the result from several other cells
similar to

C1=K5/k6 + U8/U9 + M12/M13

As you can see if the value of the cells K6 or U9 or M13 are zero there is a division by zero
and the calculation crashes. In this case the terms should be ignored.

What I need now is a precalculation-and-ignore-instruction which excludes the terms similar to

C1=ignoreiftrue(K6=0,K5/k6) + ignoreiftrue(U9=0,U8/U9) + ignoreiftrue(M13=0,M12/M13)

In more general form the function

ignoreiftrue(<condition,<expression)

should evaluate at first the condition and if it is NOT true uses the expression(=function) as usual.

Is there such a function in Excel?
