Entering an expression
TopSolid allows you to enter expressions instead of numerical values: i.e.: you can enter 45 * 15+10 instead of 685. The operators you can use in expressions are:
|
+ |
Addition |
|
- |
Subtraction |
|
* |
Multiplication |
|
/ |
Division |
|
^ |
Power |
The operators are consider from the left to the right using the following priority:
^ > * > / > + > -
However, you can use parentheses in order to calculate certain operations
before others. 
You can also use arithmetic functions in your expressions. The function argument have to be included between parentheses. The arithmetic functions you can use in TopSolid are the following ones:
