toCC -- convert to high-precision complex number

Description

Synopsis

Usage:

toCC(prec,x,y)

toCC(prec,x)
Inputs:
- prec, an integer, the number of bits of precision desired
- x, an integer, a rational number, or a real number
- y, an integer, a rational number, or a real number
Outputs:
- a complex number, the complex number with real part x and complex part y. If y is omitted, the imaginary part is zero.

i1 : toCC(200,7)

o1 = 7

o1 : CC (of precision 200)

i2 : toCC(100,7,3.)

o2 = 7+3*ii

o2 : CC (of precision 100)

Synopsis

Usage:

toCC(x,y)

toCC x
Inputs:
- x, a real number
- y, a real number
Outputs:
- a complex number, the complex number with real part x and complex part y. If y is omitted, the imaginary part is zero. The precision of the result is the minimum precision of the arguments.

i3 : toCC(3.,4.)

o3 = 3+4*ii

o3 : CC (of precision 53)

i4 : toCC(3.p100,4.p200)

o4 = 3+4*ii

o4 : CC (of precision 100)
