DIV Function
Function Gives division results.
Format DIV (x, y)
x, y: Equation
Explanation Gives results by calculating x/y and rounding down decimal points.
If x, y is either numerical value or variable, then it can be an integer, a single
precision real number or a double precision real number.
EXP Function
Function Gives the value of the exponent function against e (natural number).
Format EXP (x)
x: Equation
Explanation Takes the value of the exponent function result of the numerical value shown by
the either the numerical value or numeric variable of x.
When the value of x is more than 43.66827237527656, an operation overfl ow and
error will occur (when x is a double precision real number).
LOG Function
Function Gives natural logarithm.
Format LOG (x)
x: Equation (x>0)
Explanation Gives the numerical value of the natural logarithm (logarithm that takes natural
number e as base) shown by either the numerical value or numeric variable of x.
x must be a positive number.
MOD Function
Function Gives the remainder from integer division.
Format MOD (x, y)
x, y: Equation
Explanation Calculates x/y and gives the remainder.
If x, y are either numerical value or numeric variable, then it can be an integer, a
single precision real number or a double precision real number.
SQR Function
Function Gives the square root.
Format SQR (x)
x: Equation (x ≥ 0)
Explanation Calculates the square root of the numerical value shown by either the numerical
value or numeric variable of x.
Value of x must be more than zero.
