sqrt(expN)
val(expS)
Chapter 3. RLIB Function Table
The sqrt() function Returns the non-negative square root of expN. Don’t pass it a negative number
or it will fail I think
Returns NUMBER
Converts a string into a number.. respects the decimal point in a string
Returns NUMBER
fxpval(expS, expN)
Converts a string into a number.. assumes no decimal places in the string.. expN says where the
decimal place should go for instance if in your database you store all values in cents.. and not
dollars
Returns NUMBER
str(expN1, expN2, expN3)
Convert a NUMBER into a STRING of length expN2 with decimal precision of expN3
Returns STRING
iif(exp1, exp2, exp3)
stodt(expS)
In-line If. Basically exp1 is evaluated. If it is true (NUMBER != 0, STRING != NULL, DATE is
always true).. exp2 is evaluated and returned otherwise exp3 is evaluated and returned
Returns exp2 if TRUE... exp3 if FALSE
Converts a string into a date time.. must be in the format of YYYYMMDDHHMMSS (format sql
timestamp type)
Returns DATE
stodtsql(expS)
stod(expS)
Converts a string into a date time.. must be in the format of YYYY-MM-DD HH:MM:SS (format
sql datetime type)
