38
Register in float
32-bit value from the registers: 0X41340000 = 01000001 00110100 00000000 00000000b
Bit31 = 0: SB, sign bit. This number is positive.
Bit30 - Bit23: E, exponent. In this case: 130.
Bit22 - Bit0: M, mantissa. Here it is 3,407,872.
Z = 11.25
Float in register
Floating-point number X = 11.25
SB, sign bit. This number is positive => Bit31 = 0 / 0X00 / 0b
In this case 130 => Bit30 - Bit23 = 130 / 0X82 / 10000010b
mantissa. Here it is 3,407,872 => Bit22 - Bit0 = 3407872 / 0x340000 / 0110100 00000000
