The following calculations are implemented: +, -, *, /, ^, exp, log, ln, sin, cos, tan, asin, acos, atan. The output can be formated and rounded. The program brclc is a preprocessor so it must be run before you run LaTeX! It is recommended using a shellscript like 'testclc' which does this for you. The new command \clc{arg} is defined. The program brclc outputs a file called *.clc in which LaTeX finds the definitions needed to complete the \clc{arg}-command. The LaTeX-commands file inclusion commands are also supported.
