scale - scale a number or numbers in a value by a power of 2
SYNOPSIS
scale(x, n)
TYPES
If x is an xx-object, scale(x, n) requires xx_scale() to have been
defined; conditions on x and n and the type of value returned are
determined by the definition of xx_scale().
For other x:
x number (real or complex) or matrix
n integer
return same type as x
DESCRIPTION
Returns the value of 2^n * x.
scale(x,n) returns the same as x << n and x >> -n if x is an integer
for which 2^n * x is an integer.
EXAMPLE
; print scale(3, 2), scale(3,1), scale(3,0), scale(3,-1), scale(3,-2)
12 6 3 1.5 .75
LIMITS
For non-object x, abs(n) < 2^31
LINK LIBRARY
NUMBER *qscale(NUMBER *x, long n)
COMPLEX *c_scale(COMPLEX *x, long n)
