3.14 About Types of Numeric Relationships
There are functions in BASIC that allow trigonometric functions to be used. The
following describes how to express the trigonometric functions that can be used in
BASIC.
(1) Trigonometric Functions
• sin x
SIN(X)
• cos x
COS(X)
• tan x
TAN(X)
• arc tan
-1
ATN(A)
Use only radian angular
measurements when obtaining
trigonometric values.
Radians = Angle x
π
180
(2) Exponential functions and logarithmic functions
• e
x
EXP(X)
• logeX
LOG(X)
This is a natural log
There is no function that can directly obtain a value for log10X (standard log). Please
use log
10
X=
logeX
loge10
.
(3) Square roots
•
x
SQR(X)
(4) Numeric Conversions
• Integer conversion
INT(X)
• Absolute values
ABS(X)
• Sign
SGN(X)
• Round off decimal point
FIX(X)
(5) Random numbers
• Random numbers between 0 and 1
RMD(X)
For details on function arguments, see the detailed descriptions.
