Calculations

You can optionally enter one or more formulas for each measurement, so they can be ready to use during measurements.

Set the description and formula for the calculation of the result. Enter the left part of the formula you desire without the = symbol, inserting numbers, parameters, and functions.

Use:

·      Numbers (without the thousands separator), using the (.) as decimal point.

·      Library parameters Pi which you have already defined in the library. The values that will be used in the formulas will be the ones you set for the current project in the ‘Project measurement parameters’ window (See General/Project measurements parameters ).

·      The letters R, L, and A to symbolize the result of a measurement (Result), the measured length (Length), or the measured area (Area) respectively. In the case of measuring area, the program automatically computes the perimeter length while in the case of measuring length (using a polyline) it attempts to calculate the area as well.

·      The symbols of the mathematical operations: plus (+), minus (-), multiply (*), divide (/) and raise to power (^).

·      Parentheses for grouping parts of the expression.

·      Functions, which are input in the exact same format used in Excel.

 comment_16 There are many of the most widely used Excel functions. See the Appendix for their correct syntax. You can also refer to Excel Help.

Some of the available functions are:

ABS, ACOS, ASIN, ASINH, ATAN, ATAN2, CEILING, COS, COSH, EXP, FACT, FLOOR, LOB, ROUND, SIGN, SIN, SINH, SQRT, TRUNC

comment_16 Use the navigator at the bottom of the window to move from one entry to another or to delete an entry. Specifically, use the ,  buttons to move to the previous or next entry, the ,  to move to the previous or next page, the ,  buttons to move to the first or last entry, and finally the  button to delete an entry.
