math(5) math(5) NAME math - math functions, constants, and types SYNOPSIS DESCRIPTION This file contains declarations of all the functions in the Math Library (described in Section (3M)). For IPF, included in a compilation under the option, this file defines the types The IPF 80-bit double-extended type. An IEEE 754-compliant, 128-bit floating-point type. On HPUX, is a synonym for It defines the types A floating type, at least as wide as For PA-RISC, is For IPF, if equals 0, is if equals 1, is if equals -2, is A floating type, at least as wide as For PA-RISC, is For IPF, if equals 0 or 1, is if equals -2, is For IPF, the value of is 0, 1, or -2, according to the use of the com- piler option or It defines the following constants, which, for IPF, may be used to ini- tialize statics and aggregates: A quiet NaN (Not-a-Number) value (type A positive infinity value (type The maximum value (type representable in the type (IEEE positive infinity). The maximum value (type representable in the type (IEEE positive infinity). For IPF only, the maximum value (type representable in the type (IEEE positive infinity). For IPF only, the maximum value (type representable in the type (IEEE positive infinity). To use compile with the option. For IPF only, equivalent to To use compile with the option. It defines the following integer constants which give special-case val- ues returned by the functions: Returned by if its argument is zero. Returned by if its argument is a NaN. For IPF, it defines the following integer constants which identify the error handling method supported by functions: Indicates support for the ISO/IEC C99 specification. Indicates support for the ISO/IEC C99 exception flag specification. Defined to be if the compiler option (not the default) is used, or defined to be otherwise. It defines the following mathematical constants (type double) for user convenience: The base of natural logarithms (e). The base-2 logarithm of e. The base-10 logarithm of e. The natural logarithm of 2. The natural logarithm of 10. The ratio of the circumference of a circle to its diameter. (There are also several fractions of its reciprocal, and its square root: and The positive square root of 2. The positive square root of 1/2. For the definitions of various machine-dependent constants, see the description of the header file. To use one of the types or or one of the macros or compile with the option.
