posty [-v] -v enable stack dumps (for debugging)
In interactive mode, you have two choices:
- Enter a postfix style expression to be evaluated (supports +, -, /, *, ^, %)
- Advanced functions: sqrt, sin, cos, tan, asin, acos, atan
- Support for constants: pi and e
- Enter :N to set decimal precision, where N is the number of digits displayed to the right of the decimal. Note that this can also be part of an expression.
