Real functions take arguments with a Single or Double real type and return a result with the same type. The result cannot be implicitly cast to an integer. You can use an explicit integer type cast.

acos(Single)                  inverse cosine measured in radians
acos(Double)


acosh(Single)                 inverse hyperbolic cosine
acosh(Double)


asin(Single)                  inverse sine measured in radians
asin(Double)


asinh(Single)                 inverse hyperbolic sine
asinh(Double)


atan(Single)                  inverse tangent measured in radians
atan(Double)


atan(Single, Single)          inverse tangent of the first
atan(Double, Double)          argument (y) divided by the second (x)


atanh(Single)                 inverse hyperbolic tangent
atanh(Double)


ceiling(Single)               integer greater or equal to the argument

floor(Single)                 integer lower or equal to the argument
floor(Double)                 Dor positive numbers this is the same as:  integer(R)
