Basic floating point calculator with variables which calculate basic operations: Addition, subtraction, multiplication and division and extra functions such as absolute value, square root, exponential, natural logarithm and round. It is possible to assign variables, visualize calculator's internal state and visualize internal function's library. To run calculator you must execute the command "calc" once you have compile files, with Makefile

Execution example: $ ./calc Calculadora de punto flotante con variables...

 1 + 3/4 1.75

 x = 3e­4 / 2 x = 0.00015

 (x + 3) * 2 6.0003

 y = 2 * x y = 0.0003

 z + 1 Variable z no asignada

 #var y = 0.0003 x = 0.00015

 !round !sqr 34 Función sqr no implementada

 #func Comando func no implementado

 #fun abs : valor absoluto sqrt : raíz cuadrada exp : exponencial log : logaritmo natural round : redondeo

 !round !sqrt 34

 3,4 Error lexico

 3 4 Error sintactico

 #fin ... Adiós !!!
