The following math functions are part of global. Trig functions use or return radians, not degrees.

Abs(x as Float) as Float

Returns the absolute value of the argument.

Atn(x as Float) as Float

Returns the arctangent (in radians) of the argument; that is, ATN(X) returns "the angle whose tangent is X". To get arctangent in degrees, multiply ATN(X) by 57.29578.

Cdbl(x as Integer) as Float

Also returns a single precision float representation of the argument. Someday may return double.

Cint(x as Float) as Integer

Returns an integer representation of the argument, rounding up from midpoints. CINT(2.1) returns 2; CINT(2.5) returns 3; CINT(-2.2) returns -2; CINT(-2.5) returns -2; CINT(-2.6) returns -3.

Cos(x as Float) as Float

Returns the cosine of the argument (argument must be in radians). To obtain the cosine of X when X is in degrees, use CGS(X*.01745329).

Csng(x as Integer) as Float

Returns a single-precision float representation of the argument.

Exp(x as Float) as Float

Returns the "natural exponential" of X, that is, ex. This is the inverse of the LOG function, so X=EXP(LOG(X)).

Fix(x as Float) as Integer

Returns a truncated representation of the argument. All digits to the right of the decimal point are simply chopped off, so the resultant value is an integer. For non-negative X, FIX(X)=lNT(X). For negative values of X, FIX(X)=INT(X)+1. For example, FIX(2.2) returns 2, and FIX(-2.2) returns -2.

Int(x as Float) as Integer

Returns an integer representation of the argument, using the largest whole number that is not greater than the argument.. INT(2.5) returns 2; INT(-2.5) returns -3; and INT(1000101.23) returns 10000101.

Log(x as Float) as Float

Returns the natural logarithm of the argument, that is, loge(x) or ln(x). This is the inverse of the EXP function, so LOG(EXP(X)) = X. To find the logarithm of a number to another base b, use the formula logb(X) = loge(X) / loge(b). For example, LOG(32767) / LOG(2) returns the logarithm to base 2 of 32767.

Rnd(range as Integer) as Integer

Rnd(0) as Float

Generates a pseudo-random number using the current pseudo-random "seed number" (generated internally and not accessible to user). RND may be used to produce random numbers between 0 and 1, or random integers greater than 0, depending on the argument. 
RND(0) returns a float value between 0 and 1.
RND(integer) returns an integer between 1 and integer inclusive . For example, RND(55) returns a pseudo-random integer greater than zero and less than 56.

Sgn(x as Float) as Integer

Sgn(x as Integer) as Integer

The "sign" function: returns -1 for X negative, 0 for X zero, and +1 for X positive.

Sin(x as Float) as Float

Returns the sine of the argument (argument must be in radians). To obtain the sine of X when X is in degrees, use SIN(X*.01745329).

Sqr(x as Float) as Float

Returns the square root of the argument. SQR(X) is the same as X ^ (1/2), only faster.

Tan(x as Float) as Float

Returns the tangent of the argument (argument must be in radians). To obtain the tangent of X when X is in degrees, use TAN(X*.01745329).
