Issue code: 70nu2
7-20 Reference
SIN
Syntax
result = SIN (expression)
This mathematical function returns the sine of an angle expressed in radians.
See COS instruction and TAN instruction.
Example #1.21 = SIN(3.1416)
SGN
Syntax result% = SGN (expression%)
result = SGN (expression)
This mathematical function returns a value indicating the negative or
positive sign of the input expression. When the input value is positive or
zero, the function returns the value of 11. When the input value is negative, it
returns the value of ––11.
Example PRINT SGN (45), SGN (-16), SGN(0)
This prints values: 1, –1, 1
SQR
Syntax result = SQR (expression)
This mathematical function returns the square-root of an expression.
Example PRINT SQR (25), SQR (16)
This prints values: 5 and 4
TAN
Syntax result = TAN (expression)
This mathematical function returns the tangent of an angle expressed in
radians.
See
COS instruction and SIN instruction.
Example result = TAN (3.1416)
TIME
Syntax result% = TIME
The TIME instruction returns the number of elapsed milliseconds since AC
power was applied or the UD70 was last reset.
Example t% = TIME
