Mpexpr
Jul 20, 2023
Multiple precision math for Tcl
Mpexpr adds two new commands to Tcl, ‘mpexpr’ and ‘mpformat’. Mpexpr works much like Tcl’s native ‘expr’, but does all calculations using an arbitrary precision math package. Mpexpr numbers can be any number of digits, with any decimal precision. Final precision is controlled by a Tcl variable ‘mp_precision’, which can be any reasonable integer, limiting only the number of digits to the right of the decimal point.
Mpformat works much like Tcl’s ‘format’, except it formats multiple precision numbers in a variety of formats.
Mpexpr also includes most math functions provided by ‘expr’, as well as several new functions. Mpexpr also supports Tcl variables and nested evaluation, just like ‘expr’
