Documentation

Cast DBIntegral types to DBNum types. For example, this can be useful if you need to turn an Expr Int32 into an Expr Double.

Cast DBNum types to DBFractional types. For example, his can be useful to convert Expr Float to Expr Double.

Corresponds to the mod() function.

Round a DBFractional to a DBIntegral by rounding to the nearest larger integer.

Corresponds to the ceiling() function.

Round a DFractional to a DBIntegral by rounding to the nearest smaller integer.

Corresponds to the floor() function.

Round a DBFractional to a DBIntegral by rounding to the nearest integer.

Corresponds to the round() function.
