77 * 'M' just like 'l', except in user mode the value is
78 * multiplied by 2^20 (think Mebibyte)
79 * 'f' double
80 * user mode accepts an optional G, g, M, m, K, k suffix,

82 * g, 2^20 for M and m, 2^10 for K and k
83 * 'T' double
84 * user mode accepts an optional ms, us, ns suffix,
85 * which divides the value by 1e3, 1e6, 1e9, respectively
86 * '/' optional gdb-like print format (like "/10x")
87 *
88 * '?' optional type (for all types, except '/')

90 * 'b' boolean
