Mathematics functions
QBasic provides several functions to do mathematical calculations. A few of them are discussed
here.
SQR
Use SQR to find the "square root" of a number.
PRINT SQR(1)
PRINT SQR(4)PRINT SQR(9)
PRINT SQR(16)
PRINT SQR(25)
Output:
(^12)
(^34)
5
ABS
ABS returns the absolute value of a number. In other words, ABS converts a negative number to
a positive number (if you pass a positive number, ABS does nothing).
PRINT ABS(12)PRINT ABS(-12)
Output:
(^1212)
COS, SIN, TAN, and ATN
You can do the following trigonometric functions in QBasic:
COS (Cosine)SIN (Sine)
TAN (Tangent)
ATN (Arctangent, inverse of TAN)
