Functions

ICL provides a variety of standard functions. Functions are written in exactly the same way in ICL as in FORTRAN, and all the standard FORTRAN 77 generic functions which are relevant to the ICL data types are provided in ICL with the same names as in FORTRAN. Thus SIN, COS, TAN, ASIN, ACOS, ATAN, ATAN2, LOG, LOG10, EXP, SQRT and ABS are all valid functions. A more complete list of functions is given in Appendix A.
