Lingo Math Functions

abs(n)

returns the absolute value of n

 

atan(n)

returns the arc-tangent of n. See Sine & Cosine Definitions

 

atan(y, x)

returns the angle, in radians, between the positive x axis and the
vector [x,y]. Similar to atan(n), with a few differences as explained in Sine & Cosine Definitions

 

bitAnd(n), bitNot(n), bitOr(n), bitXor(n)

these are binary functions. Their use in animation is limited since they aren't continuous functions. See Director Help for more information.

 

cos(t)

returns the cosine of t. See Sine & Cosine Definitions

 

exp(n)

returns e^n. e is a significant number in calculus, with a value of about 2.72

 

float(n)

returns a floating point number equal to n

 

floatP(n)

returns 1 (true) if n is a float, 0 (false) otherwise

 

integer(n)

returns the integer that n rounds to

 

integerP(n)

returns 1 (true) if n is an integer variable, 0 (false) otherwise

 

log(n)

returns the natural log of n. Natural log is log base e. To use any base, use this expression: log(n)/log(base)

 

max(a,b)

returns the larger of a and b

 

min(a,b)

returns the smaller of a and b

mod

A mod B returns the remainder after long-dividing B into A

random(n)

returns a random integer between 1 and n, inclusive

 

pi()

returns the value of pi, about 3.1415926535897...

 

power(a,b)

returns a raised to b, a^b

 

sin(t)

returns the sine of t. See Sine & Cosine Definitions

 

sqrt(n)

returns the square root of n. Equivalent to power(n,.5)

 

tan(t)

returns the tangent of t. Equivalent to sin(t)/cos(t). See Sine & Cosine Definitions
