static bool	IsInt (string valnum)
	Checks if string is integer number.
static bool	IsIntGet (string valnum, bool removeFrontChars, out string resultstr, out long resultnum)
	Checks if string is integer number.
static bool	IsReal (string valnum)
	Checks if string is real number.
static bool	IsRealGet (string valnum, bool removeFrontChars, out string resultstr, out double resultnum)
	Checks if string is real number.
static string	GetValFromSuspectExp (string valIn)
	Check string to see if it is an exponential number. If so, it is converted into real number.
static string	ConvertMainFrame (string valin, string typ)
	Converts a string representing a main frame formatted number with an encoded last character into a string of a real along with sign reversal if necessary Always makes last 2 digits into decimal portion so no further divide by 100 is necessary. If special char is within input string it becomes the end char and the remaining suffix is discarded. Leading zeros are truncated so 000.12 becomes 0.12 . Codes are: {= 0 }= 0 and negate a= 1 j= 1 and negate b= 2 k= 2 and negate c= 3 l= 3 and negate d= 4 m= 4 and negate e= 5 n= 5 and negate f= 6 o= 6 and negate g= 7 p= 7 and negate h= 8 q= 8 and negate i= 9 r= 9 and negate.
static string	GetBigDecimalFromExp (string valin)
	Uses BigDecimal class to get a formatted real number from an exponential.
static string	CleanNumber (string numStr)
	Cleans non-numeric prefix and suffix characters from number. Enclosing parens which is interpreted as negative indicator and replaced with -, while leading + is removed.

Detailed Description

Helper function to manipulate numbers.

Member Function Documentation

CleanNumber()

static string VerityDotNet.NumFuncs.CleanNumber ( string numStr )

static

Cleans non-numeric prefix and suffix characters from number. Enclosing parens which is interpreted as negative indicator and replaced with -, while leading + is removed.

Parameters

numStr

string of number to check.

Returns

string starting with notok: if error

ConvertMainFrame()

static string VerityDotNet.NumFuncs.ConvertMainFrame ( string valin, string typ )

static

Converts a string representing a main frame formatted number with an encoded last character into a string of a real along with sign reversal if necessary Always makes last 2 digits into decimal portion so no further divide by 100 is necessary. If special char is within input string it becomes the end char and the remaining suffix is discarded. Leading zeros are truncated so 000.12 becomes 0.12 . Codes are: {= 0 }= 0 and negate a= 1 j= 1 and negate b= 2 k= 2 and negate c= 3 l= 3 and negate d= 4 m= 4 and negate e= 5 n= 5 and negate f= 6 o= 6 and negate g= 7 p= 7 and negate h= 8 q= 8 and negate i= 9 r= 9 and negate.

strin original string of number value

typ conversion type: ibm. Default is ibm.

Returns

result or starts with 'notok:' if error

GetBigDecimalFromExp()

static string VerityDotNet.NumFuncs.GetBigDecimalFromExp ( string valin )

static

Uses BigDecimal class to get a formatted real number from an exponential.

Parameters

valin

original string of exponential format number

Returns

string of real number

GetValFromSuspectExp()

static string VerityDotNet.NumFuncs.GetValFromSuspectExp ( string valIn )

static

Check string to see if it is an exponential number. If so, it is converted into real number.

Parameters

valIn

string to check

Returns

string of converted real number or original string. If error, starts with notok:

IsInt()

static bool VerityDotNet.NumFuncs.IsInt ( string valnum )

static

Checks if string is integer number.

Parameters

valnum

string to check. Non-numeric chars are not removed except for enclosing parens which is interpreted as negative indicator and removed

Returns

bool

IsIntGet()

static bool VerityDotNet.NumFuncs.IsIntGet ( string valnum, bool removeFrontChars, out string resultstr, out long resultnum )

static

Checks if string is integer number.

Parameters

valnum	string to check
removeFrontChars	optional bool whether to remove non-numeric chars as prefix. Default is false. Some chars are also handled like prefix - and +, as well as enclosing parens which is interpreted as negative indicator and removed
resultstr	returned final result as string false:reason if fails (decimal, empty, non-numeric)
resultnum	returned final result as integer -999999 if error

Returns

bool

IsReal()

static bool VerityDotNet.NumFuncs.IsReal ( string valnum )

static

Checks if string is real number.

Parameters

valnum

string to check. Non-numeric chars are not removed except for enclosing parens which is interpreted as negative indicator and removed

Returns

bool

IsRealGet()

static bool VerityDotNet.NumFuncs.IsRealGet ( string valnum, bool removeFrontChars, out string resultstr, out double resultnum )

static

Checks if string is real number.

Parameters

valnum	string to check
removeFrontChars	optional bool whether to remove non-numeric chars as prefix. Default is false. Some chars are also handled like prefix - and +, as well as enclosing parens which is interpreted as negative indicator and removed
resultstr	returned final result as string false:reason if fails (decimal, empty, non-numeric)
resultnum	returned final result as real -999999.99 if error

Returns

bool
