int8, int16, int32, and int64 - a signed number with the number of bits being specified in the type

uint8, uint16, uint32, and uint64 - an unsigned number with the number of bits being specified in the type

bool - boolean, typically synonym of uint8 (but don't count on that)

void - Just like in C, doesn't store anything and returns nothing.

float32 - Most languages just call this a float. 32-bit floating point number.

float64 - Most languages just call this a double. 64-bit floating point number.

Special Types

int8* - a C string. Has heavily optimized members for string manipulation.
