ICE (Interval Calculator for Engineer)


ICE is a simple mathematical calculator with very useful shortcuts for Engineer: works natively with tolerance, can run Monte Carlo analysis, uses engineer notation, includes most of the day by day functions used by engineers.


  • Works on intervals therefore ideal for worst case analysis
  • Statistic functions able to run MonteCarlo simulation
  • Graphics function plot and viewver (2D, surface, vectors)
  • Programmable: define new variable or functions (also using basic algorithms, goto and gosub)
  • Manage measurement unit on most of functions
  • Reactive expressions which self recalculate when any of their input changes, like a spreadsheet but more user friendly. Very useful on trial-error design
  • Manage complex number on the basic functions
  • Works on list and matrix of real or complex number or intervals. Useful to apply a function to several values
  • Works on polynomials: evaluation, roots, sum, multiplication, division, derivate, integrate, etc
  • Contains common engineering formulas, constants and notation (5m for 5e-3, 7u for 7e-6, 9k for 9e3...), preferred values for all tolerances
  • Uses extended interval (Kaucher Interpretation)
  • Numerical function derivation and integration
  • Vector fields (scalar and vector product, devergece, gradiente, curl)
  • Basic integer mangements (base change, GCD, LCM, ...)
  • Fast Fourier transform
  • Multi variable not linear optimizer, discrete value scanner for optimization
  • Not linear and simultaneous equation solver
  • Read and write data written in a text file
