Implicit Numeric Conversions Table (C# Reference)

The following table shows the predefined implicit numeric conversions. Implicit conversions might occur in many situations, including method invoking and assignment statements.

From

To

sbyte

short , int, long, float, double, or decimal

byte

short , ushort, int, uint, long, ulong, float, double, or decimal

short

int , long, float, double, or decimal

ushort

int , uint, long, ulong, float, double, or decimal

int

long , float, double, or decimal

uint

long , ulong, float, double, or decimal

long

float , double, or decimal

char

ushort , int, uint, long, ulong, float, double, or decimal

float

double

ulong

float , double, or decimal

  • Precision but not magnitude might be lost in the conversions from int, uint, long, or ulong to float and from long or ulong to double.

  • There are no implicit conversions to the char type.

  • There are no implicit conversions between floating-point types and the decimal type.

  • A constant expression of type int can be converted to sbyte, byte, short, ushort, uint, or ulong, provided the value of the constant expression is within the range of the destination type.

For more information, see the C# Language Specification. The language specification is the definitive source for C# syntax and usage.
