NAME
|
|
r2g - convert radians to gradians
|
|
|
|
SYNOPSIS
|
|
r2g(x [,eps])
|
|
|
|
TYPES
|
|
x number (real or complex)
|
|
eps nonzero real, defaults to epsilon()
|
|
|
|
return number
|
|
|
|
DESCRIPTION
|
|
Given x radians, return the equivalent number of gradians.
|
|
|
|
The eps controls the precision of the calculated internal
|
|
constant pi / 200.
|
|
|
|
EXAMPLE
|
|
; pi = pi()
|
|
; print r2g(pi), r2g(pi/3), r2g(2*pi)
|
|
200 ~66.66666666666666666667 400
|
|
|
|
; print r2g(pi+4i), r2g(pi/4 + 1i*pi), r2g(pi/5 + 5i*pi)
|
|
200+~254.64790894703253723043i 50+200i 40+1000i
