ATAN(a) Returns the arctangent of a.
SINH(a) Returns the hyperbolic sine of a.
COSH(a) Returns the hyperbolic cosine of a.
TANH(a) Returns the hyperbolic tangent of a.
Bit String
Functions Description
SHR(a, n) Shifts the bits in a to the right n times. Zeros are shifted in.
SHL(a, n) Shifts the bits in a to the left n times. Zeros are shifted in.
ASHR(a, n) Shifts the bits in a to the right n times. The sign bit is shifted in on
the left.
ROR(a, n) Rolls the bits in a to the right n times.
ROL(a, n) Rolls the bits in a to the left n times.
Curve Functions
Description
CRV_FIRST_X(id) Returns the x value for the first point in the curve with the
specified id.
CRV_LAST_X(id) Returns the x value for the last point in the curve with the
specified id.
CRV_INTERP_Y(id, x,
[options])
Interpolates the curve with the specified id at the given value
of x, and returns the Y value of the curve at that point.
CRV_INTERP_V(id, x,
[options])
Interpolates the curve with the specified id at the given value
of x, and returns the V (velocity) value of the curve at that
point.
CRV_INTERP_A(id, x,
[options])
Interpolates the curve with the specified id at the given value
of x, and returns the A (acceleration) value of the curve at that
point.
CRV_EXISTS(id) Returns TRUE if the curve with the specified id exists,
otherwise returns FALSE.
Array Functions Description
LENGTH(array)
Returns the number of elements in the array.
FILL(to, val, len) Fill len values with val starting at to.
Type Conversion
Functions Description
REAL_TO_DINT(a) Rounds a to the nearest integer.
DINT_TO_REAL(a) Returns a in REAL type.
DWORD_TO_DINT(a) a and its bit order remains the same, but type is changed
to DINT.
DINT_TO_DWORD(a) a and its bit order remains same, but type is changed to
DWORD.
TRUNC(a) Rounds a to an integer towards zero.
