BASIC BUILT-IN FUNCTIONS

These are Mathematical functions that are built into BASIC. Some common BASIC functions are shown below:

1. SQR(  )
2. ABS(  )
3. LOG (  )
4. SIN (  )
5. COS (  )
6. TAN (  )
7. INT  (  )
8. RND (  )
9. EXP (  )

SIMPLE BASIC PROGRAM TO ILLUSTRATE BUILT-IN FUNCTION

SQR – Finds the square root of a positive number.

10 PRINT SQR (275)

ABS – This displays the absolute value of a given number.

20 LET A = 10

30 LET B = 12

40 LET C = A + B

50 PRINT ABS(C)

60 END

 

LOG – Using natural logarithm.
