Hello all,

how can i calculate the following line?

tmp = 1234567.12345 + 34567.45678 * 12 + 0.00123 * 12 * 12 + 0.00333 * 12 ^ 3 - 0.0022

Many thanks for your help!

Not sure about the grouping, but you can practice by putting the formula into Excel. See attached

First, you need to use the WinBatch Exponentiation operator

Code (winbatch) Select

tmp = 1234567.12345 + 34567.45678 * 12 + 0.00123 * 12 * 12 + 0.00333 * 12 ** 3 - 0.0022


and as Stan mentioned you may need to add parenthesizes to change the operator evaluation order.  It all depends on the purpose of  the expression.
