This list gives a brief description of the most useful functions to
manipulate numbers in Microsoft Access VBA.
Note that functions are always followed by a pair of brackets even if -
like Rnd() - there's nothing in between them. The Access editor will
sometimes remove these brackets but by entering them you are telling
Access that you are attempting to use a function.
| Abs(<number>) |
Returns the absolute value of <number>.
|
|
Cos(<number>)
|
Returns the cosine of <number> radians. See
Sin
and
Tan
|
|
e
|
Access does not have the value of e built in. Use
Exp(1)
to calculate e raised to the power of 1 or just define
2.718281828459 as a constant.
|
|
Exp(<number>)
|
Returns
e^<number>.
See
Log
|
|
Fix(<number>)
|
Returns the whole number between <number> and zero. Identical
to
Int
for positive numbers. Be careful with negative numbers.
|
|
Int(<number>)
|
Returns the nearest whole number less than <number>. Identical
to
Fix
for positive numbers.
|
|
Log(<number>)
|
Returns the natural (base
e
)
logaritm of <number>.
See
Exp
|
|
Pi
|
Access VBA does not have the value of pi built in. Use
3.1415926536 or however many digits you require.
|
|
Rnd()
|
Returns a
random
number. Use Randomize() to control the random number generator.
|
|
Sgn(<number>)
|
Returns 1, 0, or -1 when <number> is positive, zero, or
negative.
|
|
Sin(<number>)
|
Returns the sine of <number> radians. See
Cos
and
Tan
|
|
Sqr(<number>)
|
Returns the square root of <number>. Generates a runtime error
if <number> is negative.
|
|
Tan(<number>)
|
Returns the tangent of <number> radians. Generates a runtime
error if <number> is
Pi
/4.

Cos
and
