GNU MPC
This gem provides Ruby bindings to the GNU MPC library.
Methods
Trigonometric Methods
The GNU MPC gem provides bindings to the following functions from MPC:
MPC#sin # sine
MPC#cos # cosine
MPC#tan # tangent
MPC#sinh # hyperbolic sine
MPC#cosh # hyperbolic cosine
MPC#tanh # hyperbolic tangent
MPC#asin # inverse sine
MPC#acos # inverse cosine
MPC#atan # inverse tangent
Each of these methods accepts optional arguments to specify the rounding mode, and precision, in the following fashions:
z = MPC.new(0, 1)
z.sin() # default rounding mode; precision of the receiver is applied to the return value
z.sin(MPC::MPC_RNDZZ) # MPC_RNDZZ rounding mode; precision of the receiver is applied to the return value
z.sin(MPC::MPC_RNDNN, 64) # MPC_RNDNN rounding mode; precision of both real and imaginary parts of return value is 64
z.sin(MPC::MPC_RNDNN, 64, 128) # MPC_RNDNN rounding mode; precision
# of real part of return value is 64,
# imaginary part is 128
z.sin(:rounding => MPC::MPC_RNDZZ) # MPC_RNDZZ rounding mode; precision
# of the receiver is applied to the
# return value
z.sin(:prec => 64) # default rounding mode; precision of
# both real and imaginary parts of
# return value is 64
z.sin(:pre_real => 64, :prec_imag => 128) # default rounding mode; precision of
# real part of return value is 64,
# imaginary part is 128
Either the ordered list of arguments, or the options Hash may be passed; they cannot be mixed.
