The unit MATH1 offers several fundamental arithmetic operators and mathematical/logical routines which have not been implemented in Delphi 1.0 (e.g. hyperbolic functions, tangens, cotangens, or common logarithm). The unit also contains routines to sort data, to produce different numeric formats, to generate random numbers of special distributions, etc. In addition, a special version of the Delphi str procedure is offered which makes the creation of numeric strings significantly easier.
