Intrinsic procedures Intrinsic procedure specifications Class Inquiry function. Argument X must be of type integer, real, or complex. It may be scalar or array valued. Result type, type parameters, and shape Default integer scalar. Result value Case 1 For an integer argument, the result has the value INT(LOG10(huge)), where huge is the largest positive integer in the model representing integer numbers with same kind type parameter as X. See “The Integer Number System Model” on page 474 for more information. Case 2 For a real or complex argument, the result has the value INT(MIN(LOG10(huge), –LOG10(tiny))), wherehuge and tiny are the largest and smallest positive numbers in the model representing real numbers with the same value for the kind type parameter as X. See “The Real Number System Model” on page 475 for more information. Example RANGE(X) has the value 38 for real X, whose model is described in “The Real Number System Model” on page 475, because in this case huge= (1-2 -24 )*2 127 and tiny =2 -127 . Specific forms SNGL, SNGLQ. REAL(A, KIND) Optional argument KIND 576 Chapter 11
Description Convert to real type. Class Elemental function. Arguments A must be of type integer, real, or complex. KIND (optional) must be a scalar integer initialization expression. Result type/ type parameters Real. Intrinsic procedures Intrinsic procedure specifications Case 1 If A is of type integer or real and KIND is present, the kind type parameter is that specified by KIND. If A is of type integer or real and KIND is not present, the kind type parameter is the processor-dependent kind type parameter for the default real type. Case 2 If A is of type complex and KIND is present, the kind type parameter is that specified by KIND. Result value If A is of type complex and KIND is not present, the kind type parameter is thekindtypeparameterofA. Case 1 If A is of type integer or real, the result is equal to a processor-dependent approximation to A. Case 2 If A is of type complex, the result is equal to a processor-dependent approximation to the real part of A. Specific forms FLOAT, FLOATI, FLOATJ, FLOATK. Chapter 11 577
