Function Description
ATN2(y,x) Returns the arctangent of y/x.
CEILING(x) Rounds a number up to an integer value.
COS(x) Returns the cosine of a number.
COSH(x) Returns the hyperbolic cosine of a number.
CSGN(x) Changes the sign of a number by multiplying by -1.0.
EXP(x) Returns e raised to the x power.
FIX(x) Returns the integer portion of a number. If the number
is a negative, the first negative integer greater than or
equal to the number is returned.
FLOOR(x) Rounds a number down to an integer value.
FRAC(x) Returns the fraction part of a number.
FormatFloat(x,y) Converts a floating point value into a string.
FormatFloatL(x,y) Converts a floating point value into a string and applies
any rules associated with the locale of the computer
running RTMC.
IIF(x,y,z) Evaluates an expression (x) and returns one value if
true (y), a different value if false (z).
INT(x) Returns the integer portion of a number. If the number
is a negative, the first negative integer less than or equal
to the number is returned.
IsFinite(x) Determines if a number is finite.
LN(x) Returns the natural log of a number. (Note that LN or
LOG may be used to perform the same function.)
LOG(x) Returns the natural log of a number. (Note that LN or
LOG may be used to perform the same function.)
LOG10(x) Returns the logarithm base 10 of a number.
(x)MOD(y) Performs a modulo divide of two numbers.
PWR(x,y) Raises constant x to the power of y.
RND Generates a random number.
SGN(x) Used to find the sign value of a number (-1, 0, or 1).
SIN(x) Returns the sine of an angle.
