    Mathematical Library Functions (QBASIC)


    The functions which are used to process the numeric data are called mathematical functions. Mathematical library functions of QBasic are described below with examples. 

    SQR

    It calculate and return the square root of non-negative number.

    Example:

    CLS
    PRINT SQR(144)
    END
    

    Output

    12
    

    MOD

    It returns reminder, when one number is divided by another number.

    Example:

    CLS
    PRINT 9 MOD 5
    END
    

    Output

    4
    

    INT

    It returns an integer of a give number.

    Example:

    CLS
    n = 27.5
    PRINT INT(n)
    END
    

    Output

    27
    

    CINT

    It returns nearest rounding numeric value from -32768 to 32767 as argument.

    Example:

    CLS
    PRINT CINT(3.49)
    PRINT CINT(3.51)
    END
    

    Output

    3
    4
    

    SGN

    It returns the sign of numeric value. If the number is positive it returns 1, if the number is negative, it returns -1 and if the number is 0 it returns 0.

    Example:

    CLS
    PRINT SGN(15)
    PRINT SGN(-15)
    PRINT SGN(0)
    END
    

    Output

    1
    -1
    0
    

    ABS

    It returns corresponding positive value.

    Example:

    CLS
    PRINT (-15.3)
    END
    

    Output

    15.3
    

    SIN, COS & TAN

    SIN, COS and TAN returns sign value, cosine value and tangent value respectively.

    Example:

    CLS
    PRINT SIN(1.5)
    PRINT COS(1.5)
    PRINT TAN(1.5)
    END
    

    Output

    .997495
    .0707372
    14.10142
