Equals(object?)

Indicates whether this instance and a specified object are equal.

Parameters:

• obj (Object): The object to compare with the current instance.

Returns: Boolean

true if obj and this instance are the same type and represent the same value; otherwise, false.

public override bool Equals(object? obj)

Get(int, int)

Parameters:

• row (Int32):
• col (Int32):

Returns: Single

public float Get(int row, int col)

GetHashCode()

Returns the hash code for this instance.

Returns: Int32

A 32-bit signed integer that is the hash code for this instance.
