NAME

pldexphf, pldexph, pldexphl, pldexphw, pldexphq, pldexphll, pldexphdf, pldexphd, pldexphdl, pldexphdll - load base-16 exponent of a pair-precision floating-point number

SYNOPSIS

cc [ flags ] -I/usr/local/include file(s) -L/usr/local/lib -lmcw [ ... ]

#include <mathcw.h>
#include <paircw.h>

extern void pldexphf (float_pair result, const float_pair x, int n);

extern void pldexphl (long_double_pair result, const long_double_pair x, int n);

extern void pldexphw (__float80_pair result, const __float80_pair x, int n);

extern void pldexphq (__float128_pair result, const __float128_pair x, int n);

extern void pldexphll (long_long_double_pair result, const long_long_double_pair x, int n);

extern void pldexphdf (decimal_float_pair result, const decimal_float_pair x, int n);

extern void pldexphd (decimal_double_pair result, const decimal_double_pair x, int n);

extern void pldexphdl (decimal_long_double_pair result, const decimal_long_double_pair x, int n);

extern void pldexphdll (decimal_long_long_double_pair result, const decimal_long_long_double_pair x, int n);

NB: Functions with prototypes containing underscores in type names may be available only with certain extended compilers.


DESCRIPTION

Compute the product of the second argument and sixteen to the power of the third argument exactly when the floating-point base is 2, 4, or 16.

For base 8 or 10, the result is approximate.


RETURN VALUES

The function value, x * 2**n for binary bases, and x * 10**n for base 10, is stored in the first argument, result.

ERRORS

None.
