Problem using function in awk

I created two functions that output two random variables. I want to output them in the output file. But it does not seem to work.

Code:
# Function rgaussian1(r1, r2)
# Gaussian random number generator
  function rgaussian1(r1, r2) {
      pi = 3.142
      v1 = sqrt( -2 * log(rand()) )
      v2 = 2 * pi * rand()
      r1 = a * sin(b)
      r2 = a * cos(b)
  }

# Function rgaussian2(r1, r2)
# Gaussian random number generator
  function rgaussian2(r1, r2) {

      do {
          v1 = 2 * rand() - 1
          v2 = 2 * rand() - 1
          rsq = v1 * v1 + v2 * v2
      } while (rsq > 1)

      fac = sqrt(-2 * log(rsq) / rsq)
      r1 = v2 * fac
      r2 = v1 * fac

  }

# Include gaussian distributed random numbers
  NF == 2 {
      rgaussian1(r1, r2)
      rgaussian2(r3, r4)
      print $0,$2,r1,r2,r3,r4
  }

PLSDIDEV(3plplot)						    PLplot API							 PLSDIDEV(3plplot)

NAME
plsdidev - Set parameters that define current device-space window SYNOPSIS
plsdidev(mar, aspect, jx, jy) DESCRIPTION
Set relative margin width, aspect ratio, and relative justification that define current device-space window. If you want to just use the previous value for any of these, just pass in the magic value PL_NOTSET. It is unlikely that one should ever need to change the aspect ratio but it's in there for completeness. If plsdidev(3plplot) is not called the default values of mar, jx, and jy are all 0. aspect is set to a device-specific value. Redacted form: plsdidev(mar, aspect, jx, jy) This function is used in example 31. ARGUMENTS
mar (PLFLT, input) Relative margin width. aspect (PLFLT, input) Aspect ratio. jx (PLFLT, input) Relative justification in x. Value must lie in the range -0.5 to 0.5. jy (PLFLT, input) Relative justification in y. Value must lie in the range -0.5 to 0.5. AUTHORS
