CalcuFp

New version: CalcuFP program is a calculator software (beta version), has a wide range of mathematical functions, specific functions for different subjects (ex.- IPv4 functions), Apart from being able to have on hand an wide range of functions, allows to use different numbering systems WITHOUT CHANGING MODES. We can sum operations decimal, binary and hexadecimal mixed. Example. - 25 + BIN ('111 ') + HEX (' FF ') -> this is equivalent to adding the integer 25 +7 (binary) +255 (hexadecimal) = 287. Allows use of predefined variables and constants. Creating user functions. It has a programming section through type pascal scripts (still in testing), It has a multimedia viewer to store documentation that we have on hand for our daily tasks. Aside calculators comes with color coded for resistors, inductors and capacitors. Support matrix calculation. Solving systems of n equations. Periodic table of elements. QR code generator Create new User functions with pascal script.
