Usage
Usage of this function is very simple:
Parameters are:
value either int64_t (long long) or uint64_t (unsigned long long): Value to be converted
base uint8_t (unsigned char): the "base" for the converted number, either BIN (2), OCT (8), DEC (10), or HEX (16), optional defaults to DEC (10)
prefix bool: Add a prefix onto converted number. "B" for BIN, "0" for OCT, or "0x" for HEX, optional, defaults to false
Rerurns a String
// Signed function
String int64String(int64_t value, uint8_t base = DEC, bool prefix = false);
// Unsigned function
String int64String(uint64_t value, uint8_t base = DEC, bool prefix = false);An example sketch:
#include <Int64String.h>
// LL and ULL suffixes are needed for the compiler to parse the numbers correctly
int64_t MIN_INT64 = -9223372036854775808LL;
int64_t MAX_INT64 = 9223372036854775807LL;
uint64_t MAX_UINT64 = 18446744073709551615ULL;
uint64_t UINT64 = 4527492349271ULL;
void setup() {
Serial.begin(9600);
Serial.println();
Serial.println(int64String(MIN_INT64));
Serial.println(int64String(MAX_UINT64));
Serial.println(int64String(UINT64));
Serial.println(int64String(UINT64, BIN));
Serial.println(int64String(MAX_INT64, OCT, true));
Serial.println(int64String(UINT64, HEX));
Serial.println(int64String(MAX_UINT64, HEX, true));
Serial.println(int64String(0LL));
Serial.println(int64String(0ULL, BIN, true));
}
void loop() {
}Will output the following on the Serial Monitor:
