How can one output hexadecimal floats in R?

R uses the sprintf() function to output hexadecimal floats. However, it does not support hexadecimal-floating format by default. For example, in C, we can achieve this in an alternative way using '%a'.

How can one output hexadecimal floats in R?

R uses the sprintf() function to output hexadecimal floats. However, it does not support hexadecimal-floating format by default. For example, in C, we can achieve this in an alternative way using '%a'.

Example:

num <- 10.625
hex_float <- sprintf("0x%X.%Xp0", as.integer(num), (num - as.integer(num)) * 16)
print(hex_float)
Explanation:
  • as.integer(num) → Takes the integer part.
  • (num - as.integer(num)) * 16 → Converts the fractional part to hexadecimal.
  • sprintf("0x%X.%Xp0", ...) → Produces hexa-float output.
More Difficult Number:
num <- 15.8125
hex_float <- sprintf("0x%X.%Xp0", as.integer(num), (num - as.integer(num)) * 16)
print(hex_float)
✅ Output: 0xF.Dp0
👉 Although it doesn't work quite like "%a", it's a useful technique for creating hexadecimal float representation! 🚀
