A small console application in C++ which parses and evaluates mathematic expressions.

This parser can perform all basic arithmetic operations. In addition it supports brackets and several constants and functions:

• sin(x)
  • Calculates the sinus
• cos(x)
  • Calculates the cosinus.
• tan(x)
  • Calculates the tangens.
• sqrt(x)
  • Calculates the square root.
• pow(x, y)
  • Calculates x cubed y.
• log(x)
  • Calculates the natural logarithm.
• ceil(x)
  • Rounds x upward, returning the smallest integral value that is not less than x.
• floor(x)
  • Rounds x downward, returning the largest integral value that is not greater than x.
• digsum(x)
  • Calculates the digitsum.

• e
• pi
