Frac: Fractional Part and Maximal Digits of a Numeric Value

Description

Frac() returns the fractional part of a numeric value. MaxDigits() return the number of digits in x. Ndec() returns the number of decimals. Prec() returns the precision of a number x.

Usage

Frac(x, dpwr = NA)
MaxDigits(x)
Ndec(x)
Prec(x)

Arguments

x

the numeric value (or a vector of numerics), whose fractional part is to be calculated.

dpwr

power of 10 for a factor z, the fractional part will be multiplied with. The result will be returned rounded to integer. Defaults to NA and will then be ignored.

Examples

# NOT RUN {
x <- rnorm(5)*100
x
Frac(x)

# multiply by 10^4
Frac(x, dpwr=4)

MaxDigits(c(1.25, 1.8, 12.0, 1.00000))

x <- c("0.0000", "0", "159.283", "1.45e+10", "1.4599E+10" )
Ndec(x)
Prec(as.numeric(x))
# }
