HYPSIN
PURPOSE: Returns the value of the hyperbolic sine of the argument.
FORMAT:
HYPSIN
(argument)
Numeric expression
The parenthesis enclosing the argument can be omitted when the argument is a
numeric value or variable.
EXAMPLE: HYPSIN (1.5)
PARAMETERS: argument must be within the [-230.2585092 , +230.2585092] range.
EXPLANATION:
1. The mathematical formula for hyperbolic sine is :
sinh(x) = (e
x
- e
-x
) / 2 where e is 2.7182818284590452353602874713526...
2. The returned value is in the ]-5x10
99
, 5x10
99
[ range.

HYPTAN
PURPOSE: Returns the value of the hyperbolic tangent of the argument.
FORMAT:
HYPTAN
(argument)
Numeric expression
The parenthesis enclosing the argument can be omitted when the argument is a
numeric value or variable.
EXAMPLE: HYPTAN (2.5)
PARAMETERS: argument must be within the ]-1x10
100
, 10
100
[ range.
EXPLANATION:
1. The mathematical formula for hyperbolic tangent is :
tanh(x) = (e
x
- e
-x
) / (e
x
+ e
-x
) where e is 2.71828182845904523536028747...
2. The returned value is in the ]-1 , 1[ range.
SEE: HYPATN, LN
INT
PURPOSE: Returns the largest integer that does not exceed the value of the
argument.
FORMAT:
INT
(argument)
Numeric expression
The parenthesis enclosing the argument can be omitted when the argument is a
numeric value or variable.
EXAMPLE: INT (-1.3)
PARAMETERS: argument : numeric expression
EXPLANATION:
1. Returns the largest integer, which does not exceed the value of the argument.
2. INT(x) is equivalent to FIX(x) when x is positive, and FIX(x)-1 when x is
negative.
