This chapter covers most of the calculator's functions that do com
putations on real numbers, including some numeric functions
intended for programs (such as the absolute-value function):
• Exponential and logarithmic functions.
• Trigonometric functions.
• Hyperbolic functions.
• Percentage functions.
• Conversion functions for coordinates, angles, and fractions.
• Probability functions.
• Parts of numbers (number-altering functions).
Arithmetic functions and calculations were covered in chapters 1 and
2. The advanced numeric operations (root-finding, integrating, com
plex numbers, base conversions, and statistics) are in part 3 of this
