Built-in functions

Trigonometric functions:

cos(x)	cosine of x, with x in radians
cos1(x)	cosine of x, x=0...1 for a full circle
sin(x)	sine of x, with x in radians
sin1(x)	sine of x, x=0...1 for a full circle
tan(x)	tangent of x, with x in radians

Miscellaneous functions:

abs(x) absolute value of x

mod1(x) x mod 1; i.e., the fractional part of x

pow(x,y) x raised to the power of y

round(x,y) round x to nearest multiple of y

sqrt(x) square root of x

tanh(x) hyperbolic tangent of x

Complete filters:

biquad(x,a0,a1,a2,b0,b1,b2) biquad-filter applied to x with 6 coefficients; the transfer function is H(z) = (b0 + b1*z^-1 + b2*z^-2) / (a0 + a1*z^-1 + a2*z^-2)

biquad(x,g,a1,a2,b1,b2) biquad with 5 parameters: H(z) = g * (1 + b1*z^-1 + b2*z^-2) / (1 + a1*z^-1 + a2*z^-2)
