As shipped in IRIX 6.5.15. Last changed in IRIX 6.5.5.
NAME MAXEXPONENT - Returns the maximum exponent in the numeric model SYNOPSIS MAXEXPONENT ([X=]x) IMPLEMENTATION UNICOS, UNICOS/mk, IRIX systems CF90, MIPSpro 7 Fortran 90 STANDARDS Fortran DESCRIPTION The MAXEXPONENT intrinsic function returns the maximum exponent in the real number model. For more information on the real number model, see the MODELS(3I) man page. It accepts the following argument: x Must be of type real. It may be scalar or array valued. MAXEXPONENT is an inquiry function. The name of this intrinsic cannot be passed as an argument. RETURN VALUES The result is a default integer scalar. The result has the value e , max as defined in the model, which represents numbers of the same type and kind type parameter as x. EXAMPLES On UNICOS systems, excluding CRAY T90 systems that support IEEE floating-point arithmetic, MAXEXPONENT(X) has the value 8189 for real X. On IRIX systems, MAXEXPONENT(X) returns the following values: * 128 for real X * 128 for real (KIND=4) X * 1024 for real (KIND=8) X On UNICOS/mk systems, MAXEXPONENT(X) returns the following values: * 1024 for real X * 128 for real (KIND=4) X * 1024 for real (KIND=8) X On CRAY T90 systems that support IEEE floating-point arithmetic, MAXEXPONENT(X) returns the following values: * 1024 for real X * 128 for real (KIND=4) X * 1024 for real (KIND=8) X * 16384 for real (KIND=16) X SEE ALSO MODELS(3I) Intrinsic Procedures Reference Manual for the printed version of this man page.
