Language Reference 12.3.24 Square Root Definition: Name: a**1/2 Usage: SQRT (generic) R ←SQRT(R), D ←SQRT(D), C ←SQRT(C), Z ←SQRT(Z) † SQRT DSQRT CSQRT R ←SQRT(R) D ←DSQRT(D) C ←CSQRT(C) CDSQRT Z ←CDSQRT(Z) † Notes: The argument to SQRT must be >= 0. The result of CSQRT and CDSQRT is the principal value with the real part >= 0. When the real part of the result is 0, the imaginary part is >= 0. † is an extension to FORTRAN 77. 12.3.25 Exponential Definition: Name: e**a Usage: EXP (generic) R ←EXP(R), D ←EXP(D), C ←EXP(C), Z ←EXP(Z) † EXP DEXP CEXP R ←EXP(R) D ←DEXP(D) C ←CEXP(C) CDEXP Z ←CDEXP(Z) † Notes: The result of a complex function is the principal value. † is an extension to FORTRAN 77. 256 Intrinsic Functions
