+summary: GNOME Calculator
+description: |
+  GNOME Calculator is an application that solves mathematical equations.
+  Though it at first appears to be a simple calculator with only basic
+  arithmetic operations, you can switch into Advanced, Financial, or
+  Programming mode to find a surprising set of capabilities.
+
+  The Advanced calculator supports many operations, including:
+  logarithms, factorials, trigonometric and hyperbolic functions,
+  modulus division, complex numbers, random number generation, prime
+  factorization and unit conversions.
+
+  Financial mode supports several computations, including periodic interest
+  rate, present and future value, double declining and straight line
+  depreciation, and many others.
+
+  Programming mode supports conversion between common bases (binary, octal,
+  decimal, and hexadecimal), boolean algebra, one’s and two’s complementation,
+  character to character code conversion, and more.
