Here are some excellent references about floating-point math and ways to avoid pitfalls: The Perils of Floating Point by Bruce M. Bush; Fun with Floating Point ArithmeticConversion instructions support converting between word (32-bit two's complement), single (32-bit IEEE floating point), and double (64-bit IEEE floating point). Hence, a floating point register, at any given moment, may contain an integer, a single precision floating point value, or half of a double precision floating point value.° Same Hardware as Multiply: just need ALU to add or subtract, and 64-bit register to shift left or shift right ° Hi and Lo registers in MIPS combine to act as 64-bit register for multiply and divide ° Signed Divides: Simplest is to remember signs, make positive, and complement quotient and remainder if necessarySingle precision floating-point format 1 Single precision floating-point format IEEE single-precision floating point computer numbering format, is a binary computing format that occupies 4 bytes (32 bits) in computer memory. In IEEE 754-2008 the 32-bit base 2 format is officially referred to as binary32. It was called single in IEEE 754-1985.

Example 3 double x = -0.3; double y = (float) x; Floating-point addition, subtraction, multiplication and division may overflow. An overflow means that the exponent is too large to be represented in the exponent field.
