Functions
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
