Round to multiple of aNumber

Round up to a multiple of aNumber. For roundDown use trunc.

Truncate to multiple of aNumber (e.g. it rounds numbers down to a multiple of aNumber).

Rounds the value to a multiple of **resolution**. By using **margin** and **strength** you can control which values will be rounded, and by how much.

Conceptually this is the equivalent of MIDI quantization in a DAW/MIDI sequencer. In particular it allows a certain sloppiness close to the **resolution** value.

Note: this method expects values >= 0.

resolution |
Round this value to a multiple of resolution. E.g. if you chose 1, then all values would be rounded to the nearest integer. |

margin |
Values that are within ± E.g. if you chose a resolution value of 0.5 and a margin of 0.01, then the values 0.501 and 0.499 would be left as they are, but the value 0.502 would become 0.5. This should be a value between 0 and |

strength |
Determines the degree to which this number will be changed. If strength is 1, then this function will return the nearest resolution. If it is 0, then value of this number will be left unchanged. E.g. If the resolution was 1 and strength was 0.5, then the value 0.6 would become 0.8. |

Rounds the values **margin** distance from resolution to a multiple of resolution. By using **margin** and **strength** you can control when values will be rounded, and by how much.

Conceptually this is the equivalent of 'snap' in a graphics program. Values within a certain distance (**margin**) from a grid line are snapped to it. All other values are unchanged.

Note: this method expects values >= 0.

resolution |
Snap this value to a multiple of resolution. E.g. if you chose 1, then all values would be rounded to the nearest integer. |

margin |
Only values that are greater ± E.g. if you chose a resolution value of 0.5 and a margin of 0.01, then the values 0.501 and 0.499 would be snapped to 0.5, but the value 0.502 would be unchanged. This should be a value between 0 and |

strength |
Determines the degree to which this number will be changed. If strength is 1, then this function will return the nearest resolution. If it is 0, then value of this number will be left unchanged. E.g. If the resolution was 1 and strength was 0.5, then the value 0.6 would become 0.8. |

Some methods to ease the development of generic ugen code.

`this`

false if receiver cannot be used in UGen.

A variety of Special Functions are supplied by the Boost C++ library. The library's online documentation serves as the primary reference for the following functions. The methods here match closely with those found in the source library, as do argument names.

Below you'll find descriptions of the functions and their bounds, but for visualizing the functions, have a look in Tour of Special Functions.

WARNING: Many of the functions are only valid in certain numerical ranges. For the most part, error handling happens in the underlying boost functions. While these errors are often obtuse, you'll usually find a useful message at the end of the error regarding proper ranges and the erroneous value supplied. Refer to the online documentation for more detailed descriptions, and the Tour of Special Functions for plots showing ranges and asymptotes.

Like all elliptic functions, these can be parameterised in a number of ways:

- In terms of a parameter
`m`

. - In terms of the elliptic modulus
`k`

where`m = k^2`

. - In terms of the modular angle
`α`

, where`m = sin2α`

This implementation takes the elliptic modulus `k`

as the parameter. In addition the variable `u`

is used to express an amplitude **φ**. All take the elliptic modulus as the first argument - this is for alignment with the Elliptic Integrals.
