Using Arithmetic Operations 
Using Arithmetic Operations
Basic Arithmetic Operations:
You can use the following basic arithmetic operations in dependencies to perform calculations:
+
Addition-
Subtraction/
Division*
Multiplication
CHAR_WIDTH = CHAR_LENGTH / 4
Standard Functions
You can use the following standard functions:
sin |
Sine function |
cos |
Cosine function |
tan |
Tangent function |
exp |
Exponent for base e |
ln |
Natural logarithm |
abs |
Absolute amount |
sqrt |
Square root |
log10 |
Logarithm for base 10 |
arcsin |
Arc sine (inverse function of sin) |
arccos |
Arc cosine (inverse function of cos) |
arctan |
Arc tangent (inverse function of tan) |
sign |
Sign (plus or minus sign) of x |
frac |
Decimal part of x |
SIN (2*3.14 * ANGLE / 360)
No distinction is made between upper and lower case letters in functions.
Function names are automatically converted to upper case letters.Precision and Rounding for Numeric Characteristics
You can use the following commands to round a value calculated by dependencies:
Function |
Description |
X = 3.1 |
X = -3.1 |
ceil |
Lowest integer that is not less than x |
+4 |
-3 |
trunc |
Integer part of x |
+3 |
-3 |
floor |
Highest integer that is not greater than x |
+3 |
-4 |
Use in an action:
$SELF.CHAR_A = FLOOR ($SELF.CHAR_B + $SELF.CHAR_C + 0.5)
The action calculates the sum of characteristics B and C and rounds the result to an integer.
You see the rounded value on the screen.
However, if the value is used in subsequent calculations, the exact value is used, not the rounded value.
