>=

Name

>= --  Determines if one value is greater than or equal to another.

Description

Determines if one value is greater than or equal to another.

Syntax

(a >= b ? v1 : v2)

where a, b, v1 and v2 may be expressions, but a, b not audio-rate.

Performance

In the above conditionals, a and b are first compared. If the indicated relation is true (a greater than b, a less than b, a greater than or equal to b, a less than or equal to b, a equal to b, a not equal to b), then the conditional expression has the value of v1; if the relation is false, the expression has the value of v2. (For convenience, a sole "=" will function as "= =".)

NB.: If v1 or v2 are expressions, these will be evaluated before the conditional is determined.

In terms of binding strength, all conditional operators (i.e. the relational operators (<, etc.), and ?, and : ) are weaker than the arithmetic and logical operators (+, -, *, /, & and ||).

These are operators not opcodes. Therefore, they can be used within orchestra statements, but do not form complete statements themselves.

Examples

Here is an example of the >= opcode. It uses the files greaterequal.orc and greaterequal.sco.

Example 15-1. Example of the >= opcode.

/* greaterequal.orc */
; Initialize the global variables.
sr = 44100
kr = 44100
ksmps = 1
nchnls = 1

; Instrument #1.
instr 1
  ; Get the 4th p-field from the score.
  k1 =  p4

  ; Is it greater than or equal to 3? (1 = true, 0 = false)
  k2 = (p4 >= 3 ? 1 : 0)

  ; Print the values of k1 and k2.
  printks "k1 = %f, k2 = %f\\n", 1, k1, k2
endin
/* greaterequal.orc */
        
/* greaterequal.sco */
; Call Instrument #1 with a p4 = 2.
i 1 0 0.5 2
; Call Instrument #1 with a p4 = 3.
i 1 1 0.5 3
; Call Instrument #1 with a p4 = 4.
i 1 2 0.5 4
e
/* greaterequal.sco */
        
Its output should include lines like this:
k1 = 2.000000, k2 = 0.000000
k1 = 3.000000, k2 = 1.000000
k1 = 4.000000, k2 = 1.000000
