NAME SQRT, DSQRT, QSQRT, CSQRT, CDSQRT, CQSQRT - Computes square root SYNOPSIS SQRT ([X=]x) DSQRT ([X=]x) QSQRT ([X=]x) CSQRT ([X=]x) CDSQRT ([X=]x) CQSQRT ([X=]x) IMPLEMENTATION UNICOS, UNICOS/mk, IRIX systems CF90, MIPSpro 7 Fortran 90, MIPSpro Fortran 77 STANDARDS Fortran Fortran extensions: QSQRT, CDSQRT, CQSQRT DESCRIPTION The SQRT, DSQRT, QSQRT, CSQRT, CDSQRT, and CQSQRT intrinsic functions compute the square root of their arguments. 1/2 These functions evaluate y = x . SQRT is the generic function name; the others are specifics. These are elemental intrinsic functions. They accept the following argument: x Must be of type real or complex. If i is of type real, it must be greater than or equal to zero. Vector versions of these intrinsics exist on some systems. Vector versions of the SQRT, DSQRT, CSQRT, and CDSQRT intrinsics exist on UNICOS and UNICOS/mk systems. On UNICOS/mk systems, the vector versions of these intrinsics are used when -O vector3 or -O3 are specified on the compiler command line. A vector version of the single-precision and double-precision SQRT intrinsic exists on IRIX systems and is used when -O3 is specified on the compiler command line. NOTES The SQRT, DSQRT, and CSQRT intrinsic function names can be passed as arguments; the others cannot. On CRAY T90 systems that support IEEE arithmetic, the following return values occur: SQRT(0) = 0 SQRT(-0) = -0 SQRT(x) = NaN if x < 0 SQRT(NaN) = NaN SQRT(infinity) = infinity RETURN VALUES SQRT returns the real square root of its real argument. DSQRT returns the double-precision square root of its double-precision argument. QSQRT returns the quad-precision square root of its quad-precision argument. CSQRT returns the complex square root of its complex argument. CDSQRT returns the double-precision complex square root of its double-precision complex argument. CQSQRT returns the double-precision complex square root of its quad-precision complex argument. SEE ALSO Intrinsic Procedures Reference Manual for the printed version of this man page.
