Working With Numeric Data in Recital

Certain set commands change the display format of numeric data:

• set decimals - specify the number of decimal places to be displayed

set decimals to <places as numeric>

• set fixed - determine whether the number of decimal places displayed is fixed

set fixed on | off

• set point - specify the character to be used as the decimal point

set point to [<point as character>]

• set separator - specify the character to be used to mark thousands

set separator to [<separator as character>]

Numeric Conversion Functions

• abs() - return the absolute value of a numeric

numeric = abs(number as numeric)

• cast() - perform data type conversion

expression = cast(expression as expression AS datatype as character [, width as numeric [, precision as numeric]] [null | not null])

• chr() - perform numeric to ASCII character conversion

character = chr(number as numeric)

• ctrl() - return the numeric value of a control character

numeric = ctrl(letter as character)

• currency() - perform numeric to currency string conversion

character = currency(number as numeric)

• etos() - perform expression to string conversion

character = etos(expression as expression)

• int() - return the integer value of a numeric

numeric = int(number as numeric)

• str() - perform numeric to string conversion

character = str(number as numeric [, width as numeric [, decimals as numeric [, base as numeric]]] )

• strzero() - perform numeric to zero left-padded string conversion

character = strzero(number as numeric [, width as numeric [, decimals as numeric]])

• transform() - perform expression to string conversion based on a picture formatting clause

character = transform(expression as expression, picture as character)

• val() - perform string to numeric conversion

numeric = val(string as character)

Miscellaneous Numeric Functions

• acos() - calculate the angle size in radians of a cosine

numeric = acos(cosine as numeric)

• asin() - calculate the angle size of any given sine value

numeric = asin(sine as numeric)

• atan() - calulate the angle size of a given tangent value

numeric = atan(tangent as numeric)

• atn2() - calculate the angle size for the specified cosine and sine values of a given point

numeric = atn2(cosine as numeric, sine as numeric)

• between() - determine whether an expression is between two other specified expressions

logical = between(value as expression, minimum as expression, maximum as expression)

• ceiling() - calculate the smallest integer that is greater than or equal to a given value

numeric = ceiling(limit as numeric)

• cos() - calculate the cosine of an angle in radians

numeric = cos(radians as numeric)

• dtor() - perform degree to radian conversion

numeric = dtor(degrees as numeric)

• exp() - calculate exponential value

numeric = exp(power as numeric)

• floor() - calculate the largest integer that is less than or equal to a given number

numeric = floor(limit as numeric)

• lennum() - calculate the length of a numeric value
• log() - calculate natural logarithm value
• log10() - calculate base 10 logarithm value
• max() - calculate the greater of two values
• min() - calculate the lesser of two values
• mod() - calculate the division remainder

numeric = mod(dividend as numeric, divisor as numeric)

• percent() - calculate percentage

• pi() - return the value of pi

numeric = pi()

• rand() - return a random number

numeric = rand([seed as numeric])

• round() - return a rounded numeric

numeric = round(number as numeric [, decimals as numeric])

• rtod() - perform radian to degree conversion

numeric = rtod(radians as numeric)

• sign() - return the sign of a numeric value

numeric = sign(number as numeric)

• sin() - calculate the sine of an angle in radians

numeric = sin(radians as numeric)

• sqrt() - calculate a square root

numeric = sqrt(number as numeric)

• tan() - calculate the tangent of an angle in radians

numeric = tan(radians as numeric)

Miscellaneous Financial Functions

• cagr() - calculate compound annual growth rate
• fv() - calculate the future value of a periodic investment
• payment() - calculate the payment on a loan
• pmt() - calculate the payment on a loan
• pv() - calculate the present value of equal regular payments on a loan
