xstdlib

xstdlib consists of the following routines

• xTest_Prime: test if a number is a prime number
• xrand_Set_Type: select random number generator
• xrand_Get_Type: get random number generator type
• xsrand: seed the random number generator
• xrsrand: randomly seed the random number generator
• xrand: generate a random number between -(XRANDMAX - 1) and (XRANDMAX - 1)
• xrand_d: generate number between 0 and 1
• xrand_dm: genearte number between -1 and 1
• xrand_gauss_bm: generates two gaussian random numbers with mean = 0 and standard deviation 1
• xrand_gauss: generate a single gaussian random number with given mean and standard deviation
• xrandmax, XRANDMAX: current maximum value of random number generator
• XRoundNearest: round to nearest value
• XRoundUp: round up to nearest value
• XRoundDown: round down to nearest value
• XRound2: Round an unsigned integer to the nearest power of 2 (i.e. 1->1, 2->2, 3->4)
• XRound4k: Round an unsigned integer to the nearest multiple of 4096
• XSTRING: similar to std::string; meant to seamlessly handle multi-byte characters
• xIsANumber: determines if a string starts with a number
• xIsAScientificNumber: determines if a string starts with a number in scientific notation (x.xxe+-yyy) or (x.xxd+-yyy)
• xIsWhitespace: determines if a string starts with whitespace (tabs or spaces)
• xPassWhitespace: parses a string and returns pointer to first non-whitespace character
• xPassNumber: parses a string and returns pointer to first non-number character. Can process scientific or decimal values
• xPassSeparator: parses a string and returns pointer to first non-separator character
• xPassString: parses a string and returns pointer to end of string. String is delimited by user specified identifier such as ""
• xGetNumberFromEndOfString: returns the value at the end of a string instead of the beginning.
• xGetLastWordInString: returns the last word in a string
• xParse_Command_Line_Data_Ptr: looks for a particular command line parameter and returns the value
• xParse_Command_Line_Exists: determines if a command line parameter exists
• xParse_Command_Line_Dbl: returns the value of a command line parameter with a floating point value
• xParse_Command_Line_Bool: returns the value of a command line parameter with a boolean value
• xParse_Command_Line_UInt: returns the value of a command line parameter with an unsigned integer value
• xParse_Command_Line_Int: returns the value of a command line parameter with an integer value
• xParse_Command_Line_String: returns the value of a command line parameter with a string value
• xRomanNumeralGenerator: returns a string with roman numeral representation of an integer value
• xGet_Element_Symbol: returns the element symbol based on atomic number
• xChoose_Allocation_Size_Word_Aligned: returns an allocation size that is word or page aligned
• xChoose_Allocation_Size_Word_Aligned_Quiet: simliar to xChoose_Allocation_Size_Word_Aligned but won't output nasty looking error messages
• XMin and XMax: returns the minimum and maximum of a large set of values
