log10(3M) log10(3M) NAME
log10(), log10f(), log10l(), log10w(), log10q() - common logarithm functions SYNOPSIS
HP Integrity Server Only DESCRIPTION
returns the logarithm base ten of x. is a version of it takes a argument and returns a result. Integrity Server Only is a version of it takes a argument and returns a result. is an version of it takes an argument and returns an result. is equivalent to on HP-UX systems. USAGE
To use these functions compile either with the default option or with the and the options. To use (for Integrity servers) or compile also with the option. To use any of these functions, make sure your program includes and link in the math library by specifying on the compiler or linker command line. For more information, see the at the following site: PA-RISC Only Millicode versions of the function are available. Millicode versions of math library functions are usually faster than their counterparts in the standard library. To use these versions, compile your program with the or the optimization option. For special cases, the millicode versions return the value described in the RETURN VALUE section, but do not set RETURN VALUE
If x is +INFINITY, returns +INFINITY. If x is zero, returns (equal to -INFINITY) and raises the divide-by-zero exception. If x is less than zero, returns NaN and raises the invalid exception. If x is NaN, returns NaN. raises the inexact exception whenever a rounded result does not equal the mathematical result. ERRORS
If x is less than zero, sets to [EDOM]. Integrity Server Only HP-UX functions on Integrity servers do not set by default. For setting, compile with the option. SEE ALSO

HP Integrity Server Only DESCRIPTION
returns the natural logarithm of x. is a version of it takes a argument and returns a result. Integrity Server Only is a version of it takes a argument and returns a result. is an version of it takes an argument and returns an result. is equivalent to on HP-UX systems. USAGE
To use these functions, compile either with the default option or with the and the options. To use (for Integrity servers) or compile also with the option. To use any of these functions, make sure your program includes and link in the math library by specifying on the compiler or linker command line. For more information, see the at the following site: PA-RISC Only Millicode versions of the and functions are available. Millicode versions of math library functions are usually faster than their counter- parts in the standard library. To use these versions, compile your program with the or the optimization option. For special cases, the millicode versions return the value described in the RETURN VALUE section, but do not set RETURN VALUE
If x is +INFINITY, returns +INFINITY. If x is zero, returns (equal to -INFINITY) and raises the divide-by-zero exception. If x is less than zero, returns NaN and raises the invalid exception. If x is NaN, returns NaN. When it raises no other exception, whether raises the inexact exception is unspecified. ERRORS
If x is less than zero, sets to [EDOM]. Integrity System Only HP-UX functions on Integrity servers do not set by default. For setting, compile with the option. SEE ALSO
