NAME frac - return the fractional part of a number or of numbers in a valueSYNOPSIS frac(x)TYPES If x is an object of type xx, frac(x) requires xx_frac to have been defined; other conditions on x and the value returned depend on the definition of xx_frac. For other x: x number (real or complex), matrix return number or matrixDESCRIPTION If x is an integer, frac(x) returns zero. For other real values of x, frac(x) returns the real number f for which x = i + f, where i is an integer, sgn(f) = sgn(x), and abs(f) < 1. If x is complex, frac(x) returns frac(re(x)) + frac(im(x))*1i. If x is a matrix, frac(x) returns the matrix m with the same structure as x in which m[[i]] = frac(x[[i]]).EXAMPLE ; c = config("mode", "frac") ; print frac(3), frac(22/7), frac(27/7), frac(-3.125), frac(2.15 - 3.25i) 0 1/7 6/7 -1/8 3/20-1i/4LIMITS noneLINK LIBRARY NUMBER *qfrac(NUMBER *x) COMPLEX *c_frac(COMPLEX *x) MATRIX *matfrac(MATRIX *x)SEE ALSO int, ceil, floor## Copyright (C) 1999 Landon Curt Noll#### Calc is open software; you can redistribute it and/or modify it under## the terms of the version 2.1 of the GNU Lesser General Public License## as published by the Free Software Foundation.#### Calc is distributed in the hope that it will be useful, but WITHOUT## ANY WARRANTY; without even the implied warranty of MERCHANTABILITY## or FITNESS FOR A PARTICULAR PURPOSE.
