Access Expert
26 is Part 2 of our Comprehensive Guide to Access Functions.
In today's class we will focus on Math and Type Conversion Functions. You will learn a bunch of new
functions, and new tricks with some of the functions we've covered
before. You will learn multiple functions for properly rounding
numbers, use trigonometry to calculate the height of a
building, display random customer records, build a dice
roller, and much more. Topics include:


Math Functions
 Abs, Sgn,
Round, Int, Fix, Val  Sqr, Exp, Log, Natural
Logarithms

Calculate Pi, Degrees to Radians 
Trig Functions: Sin, Cos, Tan, Atn

Mod, Integer Division, Is Divisible
 Random
Numbers: Dice Roller 
Display Random X Records

Type Conversion Functions 
CInt, CLng, CStr, CDate, CCur, etc.

Description: 
Access Expert Level 26 
Versions: 
This class was recorded with Microsoft
Access 2013. The material is valid for Access 2007 up to 2021. Access has not changed that much over the years. 
PreRequisites: 
Access Expert Level
25 recommended, as you should watch all of my
classes in order. However, if you're skipping around, you should
have at least completed the Beginner series and the first 3 or 4
levels of the Expert series where I start to cover functions.

We have covered some of these functions in previous classes, however in
this Comprehensive Guide to Access Functions we will cover those
in a lot more detail, plus learn many new functions. Today we will be
learning about Math and Type Conversion functions. We will
beging by learning about the Abs (absolute value) and Sgn
(sign) functions. We'll cover the Round function in a lot more
detail, and we'll review Banker's Rounding (Round to Evens). We'll learn
how to round to the nearest multiple of X (so, for example, round to the
nearest 10 or 500). We'll learn how to use the Val function to
pull the numeric digits from a text string, and how to convert from
hexadecimal to decimal.
Next we will learn about the Sqr (square root), Exp
(exponential), and Log (natural logarithm) functions. You will
learn how to raise a number to a power. You will learn about the
mathematical constant e (Euler's Number) and how to
calculate logarithms in any base (including 10, 2, and e).
Next we will learn about the trigonometric functions Sin, Cos,
Tan, and Atn. Access does not give us a function for Pi (3.14) so
we will learn how to calculate it using the Atn function. We will learn
how to convert degrees to radians (and vice versa). We
will use our newfound knowledge of trig to calculate the height
of a building knowing only the distance to the building and the angle to
the top of the building.
We will learn about the Mod (modulus) function and integer
division. We'll learn how to determine if a number is divisible
by X (for example, by 3 or 7). Next we will learn about the Rnd
function and how to use it to generate random numbers. We will
build a simple dice roller form where we can generate three
random dice rolls (of any sized die) and add them up.
We can then use these random number techniques to do all kinds of useful
things. For example, I'll show you how to create order/invoice
codes that consist of random numbers, or generate a list of X
random employees (let's say each month you want to conduct three
random employee reviews). These techniques will work for any kind of
random number scenario.
Finally, we will learn about the Type Conversion functions. These
allow us to convert from one data type to another. They've very handy
when importing values and they come in as text values, but you want to
convert them into proper Access data types (currency, date, etc.)
This is the 26th class in the Access Expert series. This
is the second class in my Comprehensive Function Guide series. If you're
serious about building quality databases with Access, don't miss out on
this course. Of
course, if you have any questions about whether or not this class is
for you, please contact me.
