Real–Number Functions

This chapter covers most of the calculator's functions that perform computations on real numbers, including some numeric functions used in programs (such as ABS, the absolute–value function):

„Exponential and logarithmic functions.

„Quotient and Remainder of Divisions.

„Power functions. (and )

„Trigonometric functions.

„Hyperbolic functions.

„Percentage functions.

„Physics constants

„Conversion functions for coordinates, angles, and units.

„Probability functions.

„Parts of numbers (number–altering functions).

Arithmetic functions and calculations were covered in chapters 1 and 2. Advanced numeric operations (root–finding, integrating, complex numbers, base conversions, and statistics) are described in later chapters.

Exponential and Logarithmic Functions

Put the number in the display, then execute the function — there is no need to press
